Chapter 684

After Ling Jue finished writing, he left the stage. Li Yue was stunned, and everyone was stunned. So he learned?

Just now, Miss Li only said half of the solution. Lingjue has learned it?!

Li Yue coughs twice, "coughs, Ling Jue's classmates have a good understanding. Let's continue."

Ling Jue continues to stare at the blackboard.

This time, even if Li Yue knew that he was dazed, he would not ask him to answer the questions.

After class, lingjue would literally flip through the math book, and write down everything in it.

Lu yilie turned his head and gave him a question in his hand. "Sir, this question that has been bothering me for many years, solve it."

Lingjue picked up her eyebrows and looked at him. She took over his question. "This is the math problem in junior high school."

He looked pitiful. "Yes, I've been bothering with this problem for many years, and YX has set it up. I have never solved it. I once doubted that it was wrong, but it seems that there is no problem in the law. Solve it! "

Ling Jue glanced at it lightly, "let's set the parabola) 0 (42 & gt; = a a x y focus as a, take point B (a + 4, 0) as the center, take ab ︱ as the radius, draw a semicircle above the x-axis, and let's set the intersection of parabola and semicircle and different two points m, n. Point P is the midpoint of Mn. (1) Find the value of am + an.... "

Ling Jue took out his pen and wrote, "look here, solution (1) let m, N, P on the parabola line be m ′, n ′, P ′. ︱ am + ︱ an = ︱ mm ︱ + ︱ NN ′ = XM + xn + 2a and circular equation 16)] 4 ([22 = + + + - Ya X...."

Looking at Ling Jue's hand writing on the paper quickly, Lu yilie's face was stunned, "is that ok?"

"Well, you don't see the point of the question. Here is the middle point of Mn. What you think is too complicated."

“……”

Lu yilie took what he wrote and went back to his seat to study it.

For a moment, he immediately exclaimed, "sir!"!! Oh, I see!! Hahaha! "

The students are shocked to see Lu yilie. What's the matter?

Muchen opens his eyes lazily and whitens his eyes. It's noisy. Can't he be quiet? He just fell asleep.

Lingjue's mouth is hooked. It's fun to do math problems.

This kid is very smart. He fell into the trap accidentally, and then he couldn't climb up. Wouldn't he think of another way.

Lingjue felt the mobile phone in her pocket vibrated. She took it out to have a look. It was a document sent by Feng Yulin.

Her eyes were dim, and she opened them to have a look. There were all the information about the Su family on them.

There are also photos of Su Chenwei. He is a strong middle-aged man with a strong face that is a little more tolerant.

Su Qing, the eldest young master, was raised in the name of Su Chenwei from the owner of the side support family. Even if Su Chenwei went abroad, he didn't leave the Su family. He has been developing in yunhaizhou with the name of the Su family, which is somewhat powerful.

The rest are people who live in the Su family. She wrote down one by one and went to the Su family in the afternoon. She also had a deep understanding.

Her mobile phone is still vibrating, and Feng Yulin sends several messages:

"although the owner of the Su family is Su Chenwei, there is also an old owner at home. He is more intimidating. Be careful."

"It's better not to admit that she is the second young master of the Su family. Xia Qinglian says that if she wants to make use of you, she will let the people of the Su family believe that you are the real second young master of the Su family. If you admit it, there will be a lot of trouble in the future."

Ling Jue looked and nodded, "OK."

"And watch out for Su Qing."

"Don't worry."

"And remember to think of me."

Ling Jue returned a kiss expression, "OK."
