Chapter 156: Fame

"Sure." Zhuang Tunan was not panicked at all. These teachers would at most give him freshman questions. How difficult could they be?

"Which teacher will come first?" Fang Boliang looked at the teachers again.

"The guest should follow the host's wishes. Let's ask Teacher Xiong to go first," said Gao Mingxing, a mathematics teacher at Suzhong.

Xiong Jinhua waved his hands repeatedly, "You are the guests, so you should go first."

After some shoving and pushing, Gao Mingxing finally stood on the podium. He thought about it and took out a question he had prepared in advance: factorize the polynomial x^5y - 9xy^5x5y9xy5 in the rational number range, real number range and complex number range respectively.

"This question is quite difficult. It's meant to give little Tuanan a warning." Several teachers were whispering in the audience.

He Chengxuan looked calm, for he knew that Zhuang Tunan would be able to handle it; but Zhuang Chaoying frowned, for he was not sure about this question either. The teaching quality of the High School Attached to the Cotton Mill was average, and his level naturally could not be compared with that of teachers from famous schools like Suzhong.

Zhuang Tunan was lost in thought as he looked at the question. Three minutes had passed and he hadn't started writing yet. The discussion below became even louder. "Look, he's really stumped. This little Tunan must be a limited talent."

"After all, he's only eleven years old. What were you and I doing when we were eleven? Were we still learning fractions and percentages? I'll go up and make it easier for him later."

Hearing these words, Zhuang Chaoying couldn't help but feel a little disappointed, even though he was not sure about this question either.

He Chengxuan remained calm because he knew that this was Zhuang Tunan's style. He would never be like those agile geniuses who could give the answer at the first glance at the question.

Two minutes later, a teacher couldn't stand it anymore and was about to go up to the stage to persuade Zhuang Tunan to stop so that he could switch to a simpler question.

As soon as I raised my feet, I saw Zhuang Tunan finally move, picked up the chalk and began to answer the questions on the blackboard: (Xie Yanbo, the genius boy named after Ning Bi, answered the questions on the spot)

For the polynomial x^5y - 9xy^5x5y9xy5, the result of factoring it in the range of rational numbers is xy(x^4 - 9y^4)xy(x49y4).

The result of factoring in the real number range is xy(x^2 + 3y^2)(x+3y)(x-3y)xy(x2+3y2)(x+3y)(x3y).

Factoring this over complex numbers gives us xy(x^2 + 3y^2)(x+3y)(x-3y)(x^2 + 3y^2)xy(x2+3y2)(x+3y)(x3y)(x2+3y2).

The problem-solving process was so clear that even Zhuang Chaoying, who had the worst math skills at the scene, could understand it.

At the same time, there is no omission, and those who can understand it will realize that Zhuang Tunan has a very thorough grasp of the relevant knowledge points.

Seeing the shocked looks on the teachers' faces, Fang Boling became anxious because he couldn't understand.

"Dear teachers, is Tuanan's answer correct? How many points can he get? Teacher Gao, please say something." He asked anxiously.

"Yes, there is no mistake in the process. Just based on this question, he can definitely get full marks." Gao Mingxing finally came to his senses. He had set the questions according to the level of the college entrance examination questions. He did not expect Zhuang Tunan to solve it so quickly. If it were put in the formal college entrance examination, it would be worth at least ten points.

Now the full mark of a math test is 100, which is 10 points.

"I'll take the second question!" Before the other teachers could react, Xiong Jinhua rushed to the podium. He thought about it and gave a more difficult question:

Given the function y = x^2 +(2m+1)x + m^2 - 1y=x2+(2m+1)x+m21 (mm is a real number), what value of mm makes the extreme value of yy 0?

"Hiss, isn't this a bit too difficult? If it is put on the college entrance examination paper, it will be the last question. It is worth at least 20 points." Gao Mingxing took a breath. I thought I was cruel enough, but I didn't expect he was even crueler than me.

This is an elementary differential calculus question. Students nowadays need to learn this in high school. Later, high schools gradually deleted differential calculus from textbooks, and students will only come into contact with it in college.

"You're so good, Xiong Jinhua, are you planning to put some eye drops on me?" He Chengxuan couldn't help but curse.

"Teacher, I just want to see where Tunan's limit is. If you think it is inappropriate, I will change the question?" Xiong Jinhua smiled shamelessly. He Chengxuan really taught him, so there was no last name in front of the word "teacher". He was indeed his teacher.

"No, Tunan can do it."

The classroom returned to silence, and Zhuang Tunan began to look at the questions carefully again. This time, everyone's reaction was different. They all waited quietly for him to solve the problem. Another five minutes passed and no one said a word.

Seven minutes later, Zhuang Tunan started answering questions again. His problem-solving process was still clear and smooth, just like a teacher giving examples to students on the stage. Every tiny step was written out, and finally the answer was given: when m = - 1/2, the extreme value of yy is 0.

Fang Boliang looked back at Xiong Jinhua. Before he could ask, Xiong Jinhua blurted out, "It's a textbook answer. Everything from the steps to the results is correct. He got the 20 points."

"Teacher Xiong, how many points do you think Tuanan can get in mathematics if he takes the college entrance examination now?" Fang Boliang asked immediately.

“If you can also master other knowledge points at this level, getting full marks will not be a problem.” He didn’t even say anything about being careless. Judging from the character Zhuang Tunan just showed, he would definitely not lose points due to carelessness.

As for whether the difficulty of the next college entrance examination questions will increase, unless the scope of the examination is changed and new questions that are not covered in the current high school mathematics textbooks are added, it will have no impact on Zhuang Tuanan.

Because he didn't use tricks to solve these problems, but pure strength.

The latest novel is published first on Liu9shuba!

If it were in a martial arts novel, Zhuang Tunan would not use his moves to defeat the enemy, but instead use his strong inner strength to overwhelm the enemy. No matter how fancy the opponent's moves were, it would be useless.

"Oops, I forgot to take a photo just now." Fang Boliang slapped his forehead, quickly ran to the podium, erased the second half of the answer, turned on the camera to find a good angle, and said, "Tunan, please fill in the answer I erased."

Zhuang Tunan didn't ask him why and just wrote the answer honestly according to the requirements.

"Click!" Fang Boliang immediately pressed the shutter to capture this scene.

"Tunan, come and have a drink of water and take a rest." He Chengxuan smiled proudly, pulled Zhuang Tunan to sit down, picked up the thermos and poured him a glass of water.

Fang Boliang couldn't help but glance at Zhuang Chaoying. This was originally your job, why didn't you react at all? How could he know that Zhuang Chaoying was still confused. Even if Zhuang Tunan wrote down the answer clearly, he still didn't understand.

"Very good, Tuanan has a very solid grasp of the knowledge points! Lao He, you said Tuanan has already started learning freshman mathematics? Then you don't mind if I give him a starting question, right?" Ping Zetao, the head of the Department of Mathematics at Jiangsu Normal University, was also a little itchy.

"He can try the freshman calculus and elementary limits. He hasn't started learning other content yet." He Chengxuan defined the scope.

"Okay, then I'll give you a calculus problem." After a little thought, Ping Zetao wrote a problem on the blackboard.

This time, Zhuang Tunan looked at the questions for ten minutes before he started answering them. He knew that by the time he finished this question, he would be almost done with the test.

And tomorrow, his photo will appear in Suzhou Daily, and he will become famous.
