The group pet boss is a living ancestor

Chapter 87 She should be the answer
Liang Bi had just finished speaking one second, and felt that she had been slapped in the face the next second.

Although this question is not simple, it also requires analysis and calculation.

She picked up the pen and paper to think and analyze quickly almost immediately. After solving the system of equations and confirming that the stagnation point is: (0, 0) (a, a), Liang Bi felt that she was holding the pen. One hand trembled a little.

Then she performed a more precise calculation, at the point (0, 0) there are A=0, B=3a, C=0,...

It follows that (0) is not the extreme point of the function.

So……

After calculating with (a, a), the answer is exactly the same as what Song Li wrote on the blackboard in one second.

After 5 minutes, some students who are excellent in high mathematics have already come up with the answer.

Everyone did the same thing, that is, glanced at the answers on their draft paper, and at the answers written by Song Li on the blackboard.

Then--

They all unconsciously took a deep breath, leaned back slightly, and their eyes were full of disbelief.

"This...how is it possible? Isn't Song Li a scumbag?"

"I also find it incredible... Even if IQ is [-], it is impossible to solve it so quickly."

"Could it be the answer memorized..."

"It's unlikely... This kind of question should not even be easy to memorize."

……

The students' thoughts made Song Shuwan feel a little nervous. In her eyes, it was impossible for Song Li to do this question.

What went wrong, why did she feel more and more that Song Li had become different.

Liang Bi glanced at Song Shuwan, her face was a little ugly, and even her eyes were flustered.

Song Shuwan blinked at her lightly, and gave her a 'reassuring' look.

But her heart seems to have been lifted up, and it's hard to let go.

"Well, this classmate's answer is correct, but this kind of big question is scored according to the steps, and the steps should be simply written out when the time comes for the exam."

"Dingling——" after Teacher Zhang finished speaking, the get out of class bell rang.

Song Li packed up some things on the admission ticket, got up and left the classroom.

Everyone seemed to have not reacted from the shock just now, and their eyes were unconsciously watching her direction until her figure disappeared at the end of the stairs.

After Liang Bi saw Song Li leaving the classroom, she immediately got up and walked towards Song Shuwan.

As a member of the three small groups, Wang Tongtong also hurried over.

"Shuwan Shuwan..." She sat opposite Song Shuwan and lowered her voice: "Didn't you tell us before that your sister Song Li is a scumbag? Why does she look so good today?"

"That's right, Shuwan, Liang Bi made a bet with her..." Wang Tongtong also had a worried look in his eyes: "Would it be a bit precarious, this bet is too big."

"Yes, yes, I just want to avenge my good sister. Don't you often say that she is always domineering at home, and you often bully you as an adopted daughter..." Liang Bi muttered: "Today she It’s just time to come to school, so I just want to help you show her some color.”

Song Shuwan felt very irritable when she heard what the two of them said.

It's really a group of mentally retarded people who have never seen the world.

They wouldn't be qualified to be friends with her if it weren't for the fact that she was often useful to them.

No, they are not friends now, at most two attendants.

The ugly attendant can always highlight her pure and sweet appearance.

"Oh, don't panic, you two, I know you are all out to vent my anger." Song Shuwan pursed her lips: "I thought about it just now, I think she should be the answer."
