When a referee who was responsible for changing the topic wanted to change the next topic, the middle-aged Dean Miao whispered to several referees and discussed a few words with the person in charge. Pen "Fun" Pavilion www.biquge.info

After several referees heard it, they thought for a moment, looked at the exaggerated score of nine to one, and nodded their heads.

However, their voices were so quiet that the people around them couldn't hear what they were talking about for a while!

Seeing that the next question was not carried out, the surrounding people looked at the middle-aged man and Dean Miao talking with a few referees with a little puzzlement, and the scene suddenly fell silent.

Li Jie watched the middle-aged man talking with a few referees at this time, his ears moved slightly, and when he heard the content of their conversation, he couldn't cry or laugh again.

It seems that he is indeed too dazzling to answer like this, and the competition team has to work on the last question, which is extremely difficult.

After discussion, the middle-aged man stepped up to the podium, glanced deeply at a group of people in Lincheng, and then said to everyone: "The following is the tenth question. However, this question is a bit special and will not be shown on the screen. Now I'm going to write it right on the board. ”

Everyone was a little surprised when they heard this, the topics of the knowledge contest were basically displayed through projections, and now they are taking this primitive way.

Even if they thought about it a little, they immediately figured out the key point, which must be a temporary change in the topic.

The Taicheng group was also a little surprised when they saw this situation. They turned their heads to look at the disparity in the score, and a flash of inspiration appeared on their faces, maybe this accident was their chance to turn the tables.

Soon after, the middle-aged man wrote the title on the blackboard.

The questions have graphics and numeric symbols, but they look very simple. That is, a quadratic equation, an arc and a few straight lines, sketching and drawing.

However, everyone frowned when they looked at this question.

In high school knowledge, the quadratic equation is completely beyond the scope of the superclass. Most people can only solve problems that are easy to downgrade, that is, reduce four times to two times to solve them.

However, the equation in front of us not only does not have the slightest downgrade, but also combines it with geometric knowledge to form a comprehensive problem of the integration of equations and geometry.

It is very difficult to solve this quadratic equation alone, but now it is necessary to cross the knowledge points and solve the problem of geometry, which is not as simple as one plus one.

After the middle-aged man saw everyone's expressions, he showed a slight smile, this question is the finale of the finals, this time because of an unexpected situation, take it out first to deal with it.

"The two teams don't have to rush to answer this question. Both of your teams start solving the problem at the same time, fifteen minutes later. Whoever solves the most and completes the fastest will get a point. The middle-aged man looked at the two groups of people in the audience and said solemnly. Then he took a few pieces of scratch paper and handed them to the Taicheng group and Li Jie.

Seeing this, everyone around them also showed a hint of surprise, they all understood the rules of the knowledge competition, and when they advanced to the top 16, they all had the same rules. That is, to rush to answer, to answer questions, but I didn't expect that it would suddenly change now.

However, thinking of the desperate ability of the Lincheng group, they also nodded secretly about the current rules.

That's the fairest thing!

After figuring out the key points, many people set their sights on the two groups of teams.

At this time, the Taicheng group and the Lincheng group had already followed the referee's arrangement, and their respective members began to answer questions around a table.

A group of several people in Taicheng looked at the scratch paper in their hands, and almost burst into tears, this is the first time since the competition to get the opportunity to answer the question, it is really exciting!

Knowing that this might be an opportunity to turn the tables, they also seized the time, unfolded the scratch paper on the table, picked up the pen, and prepared to start answering the questions.

However, their eyes fell on the quadratic equation on the blackboard, and they frowned again.

How do you solve quadratic equations?

After Li Jie took the scratch paper from the middle-aged man's hand, he handed it to Mu Qingqing and the others.

Mu Qingqing took the scratch paper from Li Jie's hand, picked up the pen, looked at the question on the blackboard, and also frowned.

"It's a quadratic equation, do you have to follow the method of solving it directly?"

She and Li Jie have studied the quadratic equation before, and now she still remembers the solution.

Wang Jing also looked at the topic on the blackboard.

"The general solution formula is extremely complicated, and if the equation is solved, it will not be enough time to apply it to geometry! Moreover, the solution of the solved quadratic equation must be very long, and it is more troublesome to apply it. Wang Jing is also the way.

Sun Ying looked at the topic on the blackboard with a cold gaze.

"Maybe there's something else in this problem! For example, the geometry problem below might be a simple solution to the equation. Sun Ying said in a low voice.

When Mu Qingqing and Wang Jing heard this, they nodded secretly, it seemed that there was such a possibility. Their eyes were all fixed on the topic, trying to find out the connection. But when I looked closely, I couldn't see any connection at all, and I couldn't help but be a little discouraged.

At this time, Mu Qingqing noticed that Li Jie had not spoken, and looked at the thoughtful expression of the topic on the blackboard, and couldn't help but tilt his head slightly, revealing a hint of a smile.

"Li Jie, do you see something?" Mu Qingqing said with a smile to Li Jie.

Sun Ying and Wang Jing also looked at Li Jie. It is true that Li Jie, who is the most powerful among them, has not spoken, which is indeed a bit strange.

Li Jie heard Mu Qingqing's question, and smiled silently.

He picked up a piece of scratch paper, sketched it with a pen, looked at it for a while, nodded, and sure enough.

Mu Qingqing and the three of them looked at Li Jie strangely, not knowing what riddle he was playing.

Li Jie smiled faintly, and then showed them the things written in his hand.

Mu Qingqing and the three of them took Li Jie's note, and the three heads came together, looking at the contents of it curiously.

With their current level, they are naturally able to understand it at one point.

So that's it!

A few people suddenly realized!

However, the way they looked at Li Jie was also strange, what the hell was done with this brain, and it could be seen like this.

"Now let's start writing the question!" Li Jie smiled slightly and took a piece of paper. "I'm in charge of solving the quadratic equations, and you're in charge of the geometry! Time is running out, we need to do it as soon as possible!"

Mu Qingqing and the others suddenly came back to their senses and nodded.

The quadratic equation for this problem has to be solved. Although it is extremely complicated to solve the solution, it should not be a problem according to Li Jie's strength.

Time passed drop by second, and the whole arena was left with the rustling sound of the tip of the pen falling on the scratch paper. Everyone is waiting, waiting for the final result.

Once the Lincheng team wins again, then the first round of 16 should also be born! )
