Xueba, I beg you to go and escort him quickly!

Some people have realized that if they go on like this, they will not only pay attention to themselves, but some famous schools abroad, right?

Naturally, they don't want their country's new stars to develop abroad, so they do it deliberately.

The headmaster didn't tell Xu Heng, nor did he mention this aspect.

But Xu Heng had already guessed it.

"Fine!"

"I won't take the make-up exam, but... please be sure to explain this clearly to my parents!"

The principal breathed a sigh of relief, "OK! Good! Good!"

"This Friday, I'll take you back and explain it to your parents in person! How's it going?"

Xu Heng, "Uh... there's no need. In fact, it's absolutely necessary for you, principal, to ask my parents to come."

The headmaster's attitude was very firm, "No, no, no! I'm going! I must go! Teacher Yao has been there so many times, and I shouldn't not go!"

Xu Heng shrugged, "Sleep!"

"So...Principal, do you have anything else to do? If not, I'll go first?"

The principal, "Okay! It's okay, you can go back!"

The principal looked at the back of Xu Heng leaving, and heaved a sigh of relief.

These things must be discussed with Xu Heng face to face.

After saying this, he was relieved.

He was not in a hurry to leave either.

I used the computer in the office to check the situation of the previous Mathematical Olympiads, but Xu Heng's situation has never happened.

Just when he was at a loss.

The leader of the Municipal Education Bureau called.

"Student Xu Heng has returned to school, did you know?"

Principal, "Leader, I know...and... I just talked to classmate Xu Heng about the previous decision, and he agreed."

Leader, "Then do you know why student Xu Heng came back early?"

Principal, "I asked!"

The leader said, "Hey... let's go! Now that you know everything, you must take good care of Xu Heng during this time! The final exam is only a week away, and we all have great responsibilities."

"After all, student Xu Heng handed in the paper within an hour of the Mathematical Olympiad, with full marks in the preliminaries, three solutions were given in the second exam, and the test paper of the third exam directly challenged the entire International Mathematical Olympiad, and in turn gave others the questions! "

The principal shuddered and almost threw the phone on the ground.

"Wait! Wait! Leader, what did you say?!"

The leader was taken aback, "Xu Heng handed in the paper an hour earlier..."

It was repeated.

Principal, "Damn!!!"

He couldn't help it!

He really couldn't hold back!

But in the next second, the principal immediately apologized, "I'm sorry, the leader! I'm sorry! I'm sorry! I didn't mean it, I really couldn't hold back!"

"hiss……"

The leader gasped, and said in a deep voice, "I can understand... because, when the provincial leader asked me so easily, I also lost my composure..."

I rely on! ! !

"At the same time, the provincial leader also shared with me his unrestrained swearing with some shame."

"You're the fucker...I'm the fucker...the leader is different, it's just my own mother and the fucker..."

The principal, "Uh...the leader is still educated! Knowledgeable! Skilled!"

Leader, "%%####￥..."

"So now, you should understand the importance of student Xu Heng!"

"Because of this competition, Xu Heng has been targeted by the entire Russell University Group!"

"They decided that Xu Heng is the youngest person ever to break the record of the Fields Mathematics Prize!"

"They will definitely come to find Xu Heng!"

"So we must protect Xu Heng!"

"Relevant departments have already begun to delete some news and videos about Xu Heng on the Internet."

"Please hurry up with your school work."

"..."

The leader and the principal explained a lot of things!

The principal also gradually realized that this was no longer an instruction issued by the big leaders in the province, but an instruction issued by the national education department himself.

The principal gasped.

After hanging up the phone, he froze.

Thinking of Xu Heng's performance in the International Mathematical Olympiad, he even got goosebumps all over his body.

"hiss……!"

"It's simply not human!"

"Oxford University! How could the Russell Group miss this opportunity!"

Before, the headmaster thought it was impossible!

Judging from Xu Heng's actions now, let alone looking for Xu Heng in person, even if the Russell University Group came to Yunshan High School jointly, it would not be an exaggeration to invite Xu Heng in person with eight sedan chairs!

!!!

It took him a long time to calm down.

……

As for Xu Heng who was returning to class, he just sat down.

Yue Pingting asked, "Why did you go? The principal is looking for you in a hurry."

Xu Heng waved his hand, "The principal told me that I will not be allowed to take the final exam, do you believe it?"

Geek!

Yue Pingting froze for a moment, "What, what did you say? I heard it right! This, this, this... is it true or not!"

Her beautiful eyes widened!

Xu Heng nodded, "You heard me right, what I said was that the principal won't let me take the final exam."

"why!"

Yang Kaixuan on the side also looked confused, "Xu Heng! Is it true?"

Xu Heng shrugged and said, "Really, what the school means is... don't let me put pressure on you!"

Yue Pingting, "???"

Yang Kaixuan, "???"

Don't put pressure on us, what does that mean...

They froze for a while.

But soon, they reacted.

Yang Kaixuan frowned, with dissatisfaction on his face, "Is it because the school has too much confidence in you, or it has too little confidence in us!"

Xu Heng shrugged, and said helplessly, "Actually, I want to take the exam, do you believe it?"

Yang Kaixuan was the first to shake his head.

"The ultimate dream of being a student is not to take exams. Although I love learning, I sometimes resist exams! It's great to have the opportunity to skip exams!"

"Xu Heng, why do you still want to take the exam?"

"You get full marks in every exam, okay...you..."

As he said that, Yang Kaixuan couldn't help substituting Xu Heng's perfect score situation.

"Wait! You have been out for so long and haven't studied. Can you still get full marks in the exam?"

"No...you didn't seem to study when you were in school."

"..."

The expression on Yang Kaixuan's face was agitated for a while, shocked for a while, and disappointed for a while.

In short, repeated many times.

Xu Heng looked at Yang Kaixuan and couldn't help asking, "Yang Kaixuan, are you okay? I feel like you can't control your expression, so nothing will happen."

Yang Kaixuan, "%￥%#￥..."

Yue Pingting looked at Xu Heng, and asked calmly, "Really? So, the school came to you just to make you skip the exam! Are you on winter vacation?"

Xu Heng nodded.

Yue Pingting's eyes lit up, "My God! I'm so envious!"

"But Xu Heng... if you don't take the exam, is the school really afraid that you will hit us? In fact... we have already been hit by you a lot! Everyone is getting used to it!"

Xu Heng smiled, "But... the city is not used to it!"

in the city?

in the city? ! !

city! ! !

Xu Heng, "The meeting in the city makes the decision, so it's not the school's idea, it should be the higher-ups."

Whatever the principal said to Xu Heng, Xu Heng said.

Yang Kaixuan, "!!!"

Yue Pingting, "!!!"

Xu Heng stretched his waist, "Whether it's good to go to Tsinghua University or go abroad, the desk in the class is the most suitable for me."

Yang Kaixuan, "%￥#￥￥￥%%..."

Yue Pingting, "Eh..."

Xu Heng looked at Yue Pingting, "Are there any questions you don't understand? Show me."

"Have!"

There are still many wrong questions in Yue Pinting's wrong question bank.

Just waiting for Xu Heng to come back!

Look at the question:

已知椭圆C：（x2/a2）+（y2/b2）=1（a＞b＞0）的离心率为根号下2/2,椭圆C和抛物线y2=x交于M,N两点，且直线MN恰好通过椭圆C的右右焦点。

(1) Find the standard equation of ellipse C;

(2) Line l passing through the right focus of ellipse C and ellipse C intersect at BA, two points, point P is on the ellipse, and vector OA=2vector BP, where O is the coordinate origin, find the slope of line l.

"I have no problem with the first question, please help me to look at the second question, is there any simpler way to solve the problem!"

Xu Heng looked at the question and said directly, "Do you know the simple method for the first question?"

Yue Pingting blinked her eyes, confused for a while.

She couldn't help touching the back of her head, "Do you have the first question?"

Xu Heng, "Show me how you solved the first question."

Yue Pingting said bluntly, "We know that the slope of the straight line l is not zero, so we can set the equation of the straight line l as x=my+2, and let A(x1, y1) B(x2, y2) P(x0, y0) Knowing (x1, y1) = 2 (x0-x2, y0-y2), so..."
