Training the Heavens

Chapter 156 Become famous
"Sure." Zhuang Tunan was not panicked at all. These teachers would at most give him freshman-level 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 have Teacher Xiong 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. After thinking for a while, he 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 teach little Tunan a lesson." Several teachers were whispering in the audience.

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

Zhuang Tunan stared at the question, lost in thought. Three minutes had passed, and he hadn't even started writing. The chatter from the audience only grew louder. "Look, he's really stumped. This little Tunan must be a limited talent."

"He's only eleven, after all. What were you and I doing when we were eleven? Still learning fractions and percentages, right? I'll go up and make it a little 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 extremely calm, because he knew that this was Zhuang Tunan's style. He would never be like those agile geniuses who could give the answer the first time they saw 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 change to a simpler question.

As soon as I raised my foot, I saw Zhuang Tunan finally move. He picked up the chalk and began to answer the questions on the blackboard:
(Xie Yanbo, a talented young man named after Ning Bi, solves the problem on the spot)

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

在实数范围内分解因式的结果为 xy(x^2 + 3y^2)(x+3y)(x-3y)xy(x2+3y2)(x+3y)(x3y)。

在复数范围内分解因式的结果为 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, understood 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 expressions on the teachers' faces, Fang Boliang became anxious. 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 will 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 placed 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 not a small number.

"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=x^2+(2m+1)x+m^21 (mm is a real number), what value of mm makes the extreme value of yy 0?

"Shh, isn't this a bit too difficult? It's worth at least 20 points if it's the final question on the college entrance exam." Gao Mingxing gasped. "I thought I was tough enough, but he's even tougher than me." This is an elementary differential calculus question, something students now learn in high school. Later, high schools gradually deleted differential calculus from textbooks, and students only encountered it in college.

"You Xiong Jinhua, are you going to put on a show for me?" He Chengxuan couldn't help but curse.

"Teacher, I just want to see where Tunan's limit is. If you think it's inappropriate, I'll change the question?" Xiong Jinhua smiled shamelessly. He Chengxuan had really taught him, so there was no surname 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 study 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 began answering the questions again. His solution was still clear and smooth, just like a teacher giving students an example. He wrote out every tiny step and finally gave the answer:
When m = - 1/2, the extreme value of yy is 0.

Fang Boliang turned to look at Xiong Jinhua. Before he could ask, Xiong Jinhua blurted out, "It's a textbook answer, correct from the steps to the results. 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 grasp other knowledge points at this level, getting full marks will not be a problem." He didn't say anything about being careless. Judging from the character Zhuang Tunan just showed, he would definitely not miss out on points due to carelessness.

As for whether the difficulty of the next college entrance examination questions will increase, unless the scope of the examination changes 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.

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

"Oops, I forgot to take a picture just now." Fang Boliang slapped his forehead and quickly ran to the podium, erased the second half of the answer, turned on the camera and found a good angle, "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 is supposed to be your job, right? Why don't you react at all?" He had no idea that Zhuang Chaoying was still completely confused. Even if Zhuang Tunan wrote the answer clearly, he still didn't understand.

"Very good, very good. Tuanan has a very solid grasp of the knowledge points! Lao He, you said that Tuanan has already started learning freshman mathematics? Then you don't mind if I give him a starting problem?" 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 starting to answer them. He knew that by the time he finished this question, the test would be almost over.

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