Perhaps because websites such as ESPN have just updated their draft prediction rankings, the discussion about Li Zhe has not yet ended on Twitter, and the lecture news spread quickly, and soon a large number of fans and even NBA players joined the discussion.

Spurs celebrity David Robinson wrote: "I majored in mathematics in college. I can responsibly say that this question is a bit difficult, but it is not conceptually difficult but requires problem-solving skills. I can solve it, but I want to see how Li Zhe solved it."

Thunder guard Westbrook wrote: "This is the kind of competition question. If you master the skills, you can use them directly, but if you don't know the skills, it will be very difficult. I also want to see how Li Zhe solved it."

Westbrook's high school scores were very good, especially in mathematics, with a GPA score of up to 4.3. Stanford University was even willing to provide him with some academic scholarships, but he finally chose to join UCLA with a full athlete scholarship.

After he said this, fans began to look for skills, but Celtic defender Rajon Rondo wrote directly:

"We can use the Cauchy's inequality theorem to solve it, and I hope Li Zhe can use a more advanced method."

Rondo's math scores are also great, and fans have begun to try to apply theorem to solve them.

Even so, 90% of fans still won’t solve it, but this does not prevent them from causing trouble.

"Stanford University's next game challenge to USC is a high probability of losing the game in terms of the lineup and recent situation of the two teams, but as a top university, you can first increase your momentum from academic ability!"

"Anthony Guz, come out and solve the problem quickly. You can't lose to Jamie Lee in the same position in momentum. If you can't, you can arrange players in other positions to play, such as Landry Fields."

"I have seen that the players of the two teams will play a literary battle in the game!"

Five minutes passed quickly, but no one still got the answer, and various sighs sounded in the classroom.

This situation is normal. Many people forget about their knowledge after throwing away the textbooks. Senior high school is the peak of intelligence in many people.

Li Zhe turned off his Twitter and smiled and said, "Since everyone hasn't figured it out, I'll demonstrate it."

"Wait, I'm going to record the video!" Maisie shouted, and many girls took out their cell phones.

Seeing that the girls were ready, Li Zhe played with his sleeves and walked to the blackboard.

"This question can be solved in two ways."

"Since there are sums of numbers and sums of squares on the question, the Cauchy inequality can be used according to experience."

"Please note that the square of 8 is 64, and 16 times 4 is equal to 64."

"So (1111)(A2B2C2D2)≥(1*A1*B1*C1*D), this is to use the Cauchy inequality to cleverly draw the question..."

Before he finished speaking, several people in the classroom suddenly realized and shook their heads and complained.

When Li Zhe expanded the inequality and wrote 4(16-E2)≥(8-  E2), more people reacted.

Finally, when Li Zhe wrote 5  E2-16E≤0, almost everyone understood.

"You are memorizing questions. You Chinese students are like this. You rely on experience to solve problems and do not understand the principles!" a man shouted.

This statement has been agreed by many people. In the face of knowledge, girls have abandoned their idols!

Li Zhe smiled and didn't care. He picked up the brush and wiped off the written content, and then started writing again.

"I will use another method to solve the problem. The question mentioned that ABCDE is all real numbers."

"So we set a function F(T)=(T-A)2(T-B)2(T-C)2(T-D)2≥0"

"According to the square difference formula, we expand this function to F(T)=4T2-2T(ABCD)  A2B22C2D2≥0, and then substitute the E and the values ​​into..."

Before the speech was finished, someone shouted for Delta δ≤0, because the F(T) function curve is always above the Y axis.

"This solution seems to be more advanced, but it still depends on experience, so you are a pseudo-school master!"

Someone shouted again, and the sound was like the man before.

Li Zhe looked up and found that it was Alex, who had competed for the training qualification with him, who had not spoken out before.

"Then what do you think you should be considered a real academic master?" Li Zhe was not anxious.

"Unless you solve a similar question I have in five minutes!"

Seeing that someone wanted to smash the situation, many girls opened their mouths and exclaimed, and even encouraged them to accept it quickly.

Natasha got up and wanted to stop him, but Li Zhe waved his hand and said it was okay, and then patted the blackboard.

"Okay, I'll just need three minutes for you to ask a question."

As Westbrook said, if you can find a skill in this kind of question, three minutes is enough, otherwise half an hour will be useless.

Many girls thought Li Zhe was sure to win, and stars were rising in their eyes.

Alex left his seat and walked onto the podium, picked up the chalk and started writing.

ABC=1

A2B2C2=2

A3B3C3=3

"To find the value of ABC, you must write the problem-solving process."

Alex finished writing with smugness, "You say it's only three minutes, let's start."

When Li Zhe heard this, he felt thousands of grass roaring by, and he just pretended to be bigger than pretending!

Alex definitely heard from him that it only takes three minutes to change his strategy and change a question with a relatively large amount of calculation.

Fortunately, this question is not difficult, mainly using the square sum formula and the cubic sum formula to substitute it multiple times.

After thinking about the solution, Li Zhe picked up the chalk and started writing immediately.

Solution: ∵(ABC)2-(  A2B2C2)=2(ABACBC)

∴1-2=2(ABACBC)

∴-1/2=ABACBC

∵A3B3C3-3ABC=(ABC)(A2B2C2-AB-BC-AC)

Li Zhe's writing speed is getting faster and faster, and the countdown begins to ring in the classroom.

Finally, he wrote ABC=1/6 in the last 8 seconds!

Alex's face turned and left, it was obvious that the answer was correct!

If Li Zhe didn't want to take advantage of the problem and come up with a more difficult question, he would probably not be able to calculate it.

Everything is God's will!

The girls cheered and screamed, Natasha covered her face and shook her head, and Li Zhe raised her arms to celebrate!

…

After continuously solving the problem, the girls' attention was attracted, and the tutoring went very smoothly throughout the morning.

By noon, the girls reluctantly said goodbye to Li Zhe and firmly said that they would come next time the lecture.

They have already experienced the joy of learning!

In order to express his gratitude, Natasha specially invited him to the restaurant to have a meal and chat. He wanted to refuse but couldn't find a reason.

It turns out that the reason why Natasha crams for a while is mainly because she thinks that the topic is very simple and she doesn't listen carefully in class. She waits until the surprise check before the exam and can't do it.

The two naturally talked about Breer. Natasha asked her about her future plans and warned her not to have other thoughts because of long-distance relationships, otherwise she would definitely report them.

During the afternoon tutoring, the two did not go to the classroom again, but held it quietly in a cafe.

Natasha is very smart, and she understands almost at a glance, and the two have a very tacit understanding, and it takes much less time than she imagined.

By the evening, Natasha invited him to attend PART again, but he decisively refused.

…

Meanwhile, photos and videos of Li Zhe PK with Alex have been posted on Twitter.

David Robinson, Westbrook and Rondo strongly praised Li Zhe. Fans analyzed the problem-solving ideas. For a time, this matter became a hot topic. ESPN and other media followed up with reports.

Just as everyone was having a happy discussion, the official Twitter update of Stanford University basketball team.
Chapter completed!
