Chapter 81 Math Class

Fu Lingyan looked at Fang Chao beside her and said, "Do you know this question?"

Fang Chao nodded subconsciously and said, "It's okay, it's quite simple."

"..."

I feel that I can no longer chat properly. Fu Lingyan is so tired. She used to be the first in the junior high school class, and she was also the top five in her age group. feel.

Everyone here is strong, and the elites selected by various middle schools may not be inferior to her in terms of overall strength. Fu Lingyan felt a little pressure, especially in front of her deskmate, the pressure was even stronger.

Mom, am I retarded?
Fu Lingyan had such an idea in her heart.

While Fu Lingyan had such an idea, Fang Chao was also surprised. He didn't expect that there were four other people who would do this question. What his mother said was indeed right. One should keep a low profile. How did he first arrive? He had just been promoted. When I entered high school, five people could solve a problem given by the math teacher at the same time. How could this not show how powerful these people were? I might not be much better than these people.

So interesting!
How can a thriving show one's own strength?

30 years in Hedong, 30 years in Hexi, don't bully the young and poor.

You math masters, just wait for me. It won't take long before I'll beat you all down!

Fang Chao, who had just finished his military training, felt a little tired in all aspects of his body, but in terms of spirit, he was definitely as excited as a chicken blood.

High school math, what a thrill.

That's right.

Only in this way can he arouse his interest.

Only difficult things will make people's heart beat even more when they are challenged, making people so excited that they can't sleep, and even the blood in their bodies is constantly boiling.

Zheng Yihang obviously didn't expect that five people would raise their hands at the same time for the question he asked. If there were only one or two people, he would still understand. It seems that the students in this class are even better than he thought.

He nodded involuntarily, and then said, "Then all five of you come up and solve this math problem for me."

"Yes."

"Yes."

"Yes."

"..."

The five people got up at the same time and glanced at each other, all seeing sparks from each other's eyes.

These individuals are all enemies. I originally thought that I was the only one who could solve the problem, so that I could pretend to be a hand-me-down in the first lesson of mathematics, but who would have thought that this force would be divided into five parts. , each copy must take away some of the light from these people's attention.

Since he is not the only one, he must become the only one and compare all these individuals.

Fang Chao is so excited, come on, come on!

Five people got the chalk at the same time, and then each ruled one side.

Five-legged confrontation!

∵(CRA)B∩{2}
∴ 2∈B
Fang Chao glanced at the others and said, "I'll go, these people write so fast. Do their hands have convulsions?"

He didn't dare to neglect, and hastened to speed up.

∵B{x|x2-5x+q=0}有4-10+q=0，∴q=6。

∵B{x|x2-5x+6}={2，3}
Assuming there are 3 in CRA, then (CRA)∩B={2, 3} contradicts (CRA)∩B={2}.

When the five people on the podium were writing the answers, the students below were stunned and came up with some unstoppable ideas about whether I was stupid or not.

City No. [-] Middle School is really a place where Crouching Tiger, Hidden Dragon, everyone is so powerful, and everyone is so good at pretending!

Are we going to swim in this pressing sea for the next few days?
too difficult……

want to cry.

All the proud children of heaven, only on the first day of formal school, they developed an attitude of skepticism about life.

At this moment.

The five people on the blackboard wrote down the remaining answers almost in no particular order.

∵3∈R and 3(RA)
∴3∈A，由A＝{x|x2＋px＋12＝0}有9＋3p＋12＝0
∴ p = -7
∴p+q=-1
After the five of them finished writing, they held the chalk in their hands.

Zheng Yihang looked at the five people's answers and said immediately, "Very good, all correct. What are your names?"

"Lin Hai."

"Fu Shaohua."

"Pan Mingming."

"Guo Xiling."

"Fang Chao."

Yes, among the five people, there is another girl. She is as good as any other girl. She is no worse than the other boys in mathematics. It can be said that the second one put down the chalk, only a few seconds slower than the first one. For a few seconds, there is absolutely no doubt about his strength.

Who said women are inferior to men?At least Guo Xiling didn't think she was worse than these people.

"Okay, I've made a note of you five, you go back to your seats first."

Zheng Yihang continued to give instructions. The topic he asked just now was not about the content of junior high school, but the knowledge of high school. It can be seen that these five people still have some knowledge of mathematics after graduating from junior high school. But these are all good things, there is no harm in getting in touch first.

But these people still can't do it. Some gifted students can get such grades in their early teens.

The expressions of these five people just now showed that they were very satisfied with themselves.

Are you satisfied with this?Is there any pursuit left?What a disappointment.

Then, Zheng Yihang smiled again, "Okay, after the test just now, then I will tell another story."

"Teacher, tell me."

"what story?"

"I didn't expect you, Mathematics teacher, to tell stories... I'm so looking forward to it..."

郑一航转身，在黑板上写下了1.052＝1，1.053＝1.16，1.054＝1.22，1.055＝1.28。

"Huh? What is the teacher writing?"

"I don't understand, isn't he going to tell a story?"

"What is this for now?"

"Are high school math teachers all this mysterious?"

A group of people were chattering, and only a few people were staring at the numbers on the blackboard, obviously thinking that the math teacher couldn't just tell stories.

After writing that line of figures, Zheng Yihang said, "A certain city built 2008 million square meters of new housing in 100, including 25 square meters of affordable housing. %, of which the economically affordable housing increases by 5 square meters per year. According to this plan, which year will the area of ​​affordable housing built in that year exceed half of the area of ​​newly built housing for the first time? Well, students, refer to the data on the blackboard, and then Tell me the exact year between 10 and 2010?"

"Fuck, fuck!!"

"Teacher, you cheated us!!"

"There is no title for this question, how should I answer it? This question is not difficult...I'm going to cry, Mr. Zheng is so good at playing..."

"Who can tell me what the math teacher said just now?"

　Thank you for the 500 starting coins rewarded by the children's shoes of "Youth is still a long way to go".
