The two sparrows seemed to be in love.

The male sparrow spoke, "Do we still want to continue kissing?"

The female sparrow spoke, "No, no... the description of kissing is too easy to be blocked..."

The male sparrow spoke, "Yes, it cannot be described below the neck."

The female sparrow continued: "Die~"

The male sparrow spoke, "Then will we continue to talk?"

The female sparrow continued, "Farewell, no one is allowed to become a sperm after the founding of the country."

The male sparrow spoke, "That stupid × is still looking at us?"

The female sparrow continued, "Don't worry about the fool, let's fly away..."

"Chirky chirp~"

"Chirky chirp~chill"

"Chirky~"

...

It is not clear what the two sparrows are doing. In his eyes, the existence of the two sparrows is like two special points. The sparrow on the left can be regarded as a movable x1 point, and the sparrow on the right can be regarded as a movable y1 point.

Set two movable x1 and y1 points in the original interval.

Setting up a binary quadratic equation will lead to two completely different answers. The question mentioned is to get the maximum area of ​​the interval, so the two answers take the maximum value, so as to obtain the values ​​of x1 and y1, substitute it into the formula, and get the answer.

Perfect ~

marvelous!

I am such a genius.

Time consumed.

Fang Chao took a look at the time.

Time taken: 56 minutes.

Compared to the previous test paper, it took ten more minutes, but Fang Chao did not think that there was anything. The test paper was definitely more difficult than the previous one.

"Teacher Lin is so scary. He must have prepared the simplest test paper to answer for me first, and then the more he gives me the test papers, the harder it is. This is to slowly destroy my willpower and make me lose confidence in mathematics..."

"But Teacher Lin, do you underestimate me too much? I am a big god. I love studying. I have an unprecedented passion for mathematics. There is nothing else in my heart. I just want to learn mathematics well."

"Hmph, start the next one, Hubei test paper, let me see what you are, it can be called hell mode, Hubei, I'm here!"

Fang Chao took a sip of water and picked up his pen to enter the test paper.

Lin Haifeng glanced at Fang Chao and was stunned for a moment. In fifty-six minutes, has he completed one?

Although it is just one test paper, adding the previous test paper as the basis is equivalent to the two test papers taking less than two hours together. Moreover, the more you use the brain power, the more you consume it. This is not easier than physical work. Long-term high-intensity math tests can easily cause mental problems. The most serious thing is that the hair volume will decrease and decrease.

There is not much hair on my head.

Fang Chao is not old yet, so he can't be bald at this time.

Therefore, in order to take into account Fang Chao's mathematical ability improvement and not to let Fang Chao's mental energy consume too much, he controlled his time to about six hours. At such a time point, it just happened to allow people to freely express themselves without excessive energy consumption.

The maximum number of test papers he expected was four, usually three were the best.

However, now, before noon time has arrived, Fang Chao has completed two test papers.

Following this progress, six hours will be the rhythm of completing six test papers against the will of heaven? I... I don't seem to bring so many test papers.

Although there are in the office, they are all regular test papers, which are used to deal with Fang Chao too much. It may take only twenty minutes to solve a test paper, which is too insulting.

"Let me see if the Hubei test paper can help me trap you for a while!" Lin Haifeng thought viciously in his heart, and placed his hope on the Hubei test questions.

Twenty minutes later, Fang Chao was still stuck on the second-last question for multiple-choice questions.

"So strong! It's worthy of being in hell mode. It has almost doubled my answer time, but do you think this will stop my pace? Hahaha, you don't take me seriously, I'll kill you!!"

Fang Chao held the decimal system in his left hand and the quadratic function in his right hand. He made drastic moves, killing this multiple-choice question so hard that his blood was splattered and his eyes were full of ferociousness. On the whole multiple-choice question, there were numbers that belonged to it after decomposition, English letters, and some addition, subtraction, multiplication and division.

In the end, Fang Chao got the multiple-choice question done.

"No matter how powerful the prey is, it can't escape the cunning hunter, hum!"

Fang Chao's face was full of pride. It was not easy to handle this multiple-choice question. He actually delayed it for about ten minutes, but it was still useless. After ten minutes, he was killed so much that he had no power to resist. Fang Chao successfully got all the multiple-choice questions.

"Well, the Hubei test papers are indeed a bit perverted... Are these teachers who set questions still humans?"

"Well, there is also Jiangsu's purgatory mode. I have not been exposed to it yet, but those who set questions must be the big devil..."

"The newbie is trembling..."

Although they have a system, Fang Chao still knows that there are people outside of people and there are heavens outside of heaven, and these people should not be underestimated.

Some people are born with amazing talents, can speak well at the age of three, can recite the role model at five, can make functions at seven, and may be exposed to some quantum mechanics at ten years old. They cannot be called human beings.

Those are all prides of heaven. Although Fang Chao has a systematic approach, he is difficult to compare with those powerful people from scratch. The future learning path is still long. He needs to continue to hone his skills and eventually enter the ranks of geniuses, go along with those prides of heaven, and even surpass them.

This is a long way to go...

But Fang Chao was full of energy and eager to try.

Immediately after filling in the blanks, Fang Chao seemed to be transformed into Nezha, with three heads and six arms. One hand can hold a one-element quadratic equation, a binary quadratic equation, a sole theorem, and the other hand holds a quadratic function, a root quadratic deformation, a simple enumeration method, and a logical, thinking, and examples jump in his eyes.

Three heads and six arms attack.

Combination skills!

Triple combination skills!

Use your hands alternately! Hot Wheels!

These special skills were controlled by Fang Chao and fully demonstrated their original abilities, and the charm of mathematics lies here.

It is not singularity. There can be countless root formulas, algorithms, formulas, etc. in a question at the same time, and these formulas require you to split, decompose, and finally combine them.

The question is dead, and people live.

The process of solving problems is also the most attractive thing about mathematics. Its charm attracts these people all the time.

Twenty minutes later, Fang Chao killed all these fill-in-the-blank questions!
Chapter completed!
