After reading the test rules, the papers were quickly distributed to everyone.
The paper is divided into three questions.
Let a and B be the two points on the hyperbola x? Y? 2 = Z, the point n (1,2) is the midpoint of the line AB, and the vertical bisector of the line AB intersects the hyperbola at the two points of C. D.
Please determine the value range of Z.
"Damn it, is it so hard?"
"Teacher, you want to kill us, don't you?"
"Coach, I can't do it."
“……”
Just seeing the first question, the whole auditorium was full of wails.
This problem seems to be very short, but the use of knowledge is extremely rich.
It covers almost all the knowledge points of the whole high school.
Even if the people sitting here are all learning hegemony level existence, but get this problem, also can't help but grasp the head.
Hard, it's too hard.
"Hey, who made this question? Isn't it a deliberate attempt to scold?"
Qin Luo saw through everything at a glance, and without much hesitation, he started to work directly!
Let AB's equation be: y = K (x-1) + 2, and bring it into hyperbolic equation
…… So the value range of Z is (- 1,0) U (0, + ∞).
Qin Luo worked hard to write down the problem-solving process, until now, he only took only three minutes.
"It's done. It's 10 points." Qin Luo breathed a long sigh of relief and burned many brain cells.
After checking, Qin Luo looked around.
On the left side, a boy is shivering, and on the right side, a girl is biting the pen and sweating Where Qin Luo's eyes can reach, there is no one to write.
“……” Is it really so hard? Qin Luo doesn't think so.
All of a sudden, Qin Luo's eyes are choked, and he sees Bai Chong sitting in the corner.
Different from other people's thinking, Bai Chong is writing fast.
A black neutral pen in his hand across a wonderful arc, the next moment, the answer has jumped on the paper.
Well, to be a Xueba in Chengyu No.7 Middle School, you really have two brushes.
But Qin Luo doesn't care. Bai Chong has two brushes, but he has dozens.
To Qin Luo's surprise, since Lin Shanshan is also writing fast.
Well, it seems that I do have the potential to be a teacher. In just a few days, I turned the learning dregs into learning bullies.
All of a sudden, Qin Luo only felt a dark in front of him and looked up: "hold the grass, there is a man!"
I saw a invigilator wearing a Zhongshan suit and a serious expression was staring at himself.
The burning eyes, as if the next second will melt him.
"What are you looking at? Do it quickly." Feng Huadong said coldly.
Feng Huadong, the invigilator of this time, is also the president of the Association for the number of southwest provinces.
”…… Teacher, it's frightening to death. "
" scared you to death? You almost scared us to death. "Feng Huadong thought.
Zhou's guess is that a senior high school student has solved a difficult problem that has plagued the mathematical community for more than ten years. When he heard the news, he was almost scared to death.
No one could have imagined that a student still in high school could prove Zhou's conjecture.
I scared you to death? Ha ha Funny.
"Do it quickly!" After a drink, Feng Huadong turned around and left.
"Are invigilators so fierce now?" Qin Luo shook his head and threw himself into solving the problem again.
A few minutes later, Qin Luo began to write hard again.
Please report us if you find any errors so we can fix it asap!
