When a group of people in Lincheng began to divide labor and solve the problem, the heads of the group in Taicheng fell into a mush. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The quadratic equation on the blackboard is not a multivariate quadrangle, but a simpler unary quadrangle. Compared with the unsolved unary equation above the fifth degree, this quadratic equation has the common methods of solving the problem summarized by the ancestors, one is the Ferrari method and the other is the Cartesian method.

Because they participated in the knowledge competition, they listened to the teacher who led the team to briefly explain the problem solving method during the knowledge competition training. One of the members of the Taicheng group still remembered one of the methods, but when they actually started to solve it, their heads suddenly became big.

These four equations are so difficult to solve, and they have to verify each step repeatedly, and they are extremely computationally intensive. With the passage of time, the entire Taicheng group was also immersed in the complex calculation process.

Another six minutes have passed, and with the time previously discussed, almost seven minutes have passed.

Li Jie slowly stopped the pen in his hand, looked down at the results he had written, and nodded secretly. There is nothing boring about these quadratic equations, but there are more calculations and problem solving steps.

Even if he tried to simplify the unnecessary steps, the process of solving the problem was written on a whole sheet of paper.

After looking down and inspecting, Li Jie turned his gaze to Mu Qingqing and the four, who were responsible for the solution of the quadratic equation, and they were responsible for the geometric figure.

This question is actually a test of the division of labor among the members of the competition!

Quadratic equations and geometric problems are actually completely independent problems! If you see the trick and simply replace the formula, you can completely separate the geometry of quadratic equations independently.

Finally, the integration is carried out, and the problem is completed.

Geometry problems are a little more difficult than quadratic equations in general, and the amount of calculation is greater, and they are still dividing and calculating, which seems to be the key point in the end.

Another two minutes passed, and the total time had passed nine minutes, with the last six minutes left.

Mu Qingqing and the others breathed a sigh of relief, looked at the final answer, and then raised their heads to look at Li Jie.

Then he looked speechlessly at him turning the pen easily, looking left and right, and didn't seem to be nervous at all.

Li Jie also noticed at this time that Mu Qingqing and the others were looking at him.

"How is it done?" Li Jie smiled.

"You've already finished it, why didn't you come to help us, you were lazy?" Mu Qingqing pursed her lips and said in a low voice of dissatisfaction.

The amount of calculation for this geometry problem is so large that Li Jie didn't even come to help!

"Alright, alright, I know it's wrong. Li Jiele smiled. "Let's finish the problem first! Time is running out now!"

Mu Qingqing also nodded when she heard this, and handed the piece of paper with the title written on it to Li Jie.

Li Jie took the piece of paper, took the paper that he had sketched before solving the problem, and compared it with the substitution formula on it, and integrated the solution of the quadratic equation with the solution of the equation of the geometric problem.

Mu Qingqing, Sun Ying, and Wang Jing also turned their heads over when they saw Li Jie carrying out the final integration.

As the equation was transformed, they were surprised to find that the solution of the equation and the solution of the geometric problem were eliminated from each other, and finally turned into a very simple algebraic formula.

"It seems that we should not be wrong!" Li Jie smiled. In fact, these topics are specially designed. The final answer is certainly very simple.

Now this phenomenon of mutual disappearance is certainly not a coincidence, it is completely the result of some people's design!

Ten minutes later, Li Jie and the others successfully solved the problem.

Li Jie and a few people took a brief look at it and saw that there was no problem. Then Li Jie took the three answers and walked towards the referee's seat.

When everyone around saw the situation of the Lincheng group, their eyes fell on Li Jie, who got up.

It's only been ten minutes, and it's over!

It was the Taicheng group that was engaged in intense calculations, and they all took the time to raise their heads. Noticed the situation of the Lincheng group.

How could it be solved so quickly, they have just calculated the solution of the quadratic equation now, and the geometric part has not yet moved.

"We're done, now submit your answer!"

The handsome boy really spoke out what they feared.

They're really done!!

When the referees saw Li Jie submitting the question, they also glanced at Li Jie deeply, and then handed three pieces of paper with answers to the middle-aged Dean Miao.

This question was given by Dean Miao, and they didn't know the answer, so they could only be judged by Dean Miao.

Dean Miao, a middle-aged man, took three pieces of paper from the hands of the referees, and at first glance, he swept to the final answer and the process of eliminating each other.

"Not bad, not bad!" said the middle-aged Dean Miao, who couldn't help but admire. He didn't have to look at anything else now, he knew that the Lincheng group had already solved this problem.

The middle-aged Dean Miao's voice was not lowered, and everyone around him suddenly understood that this problem should be solved correctly.

A group of several people in Taicheng also looked dead when they heard this.

Even if you do the same right question, you are powerless!

"Although we have already lost, we can't embarrass our school, teachers and classmates! We also have to finish this problem!" At this time, the boy who led the team in Taicheng said to his teammates with a depressed face.

When several people on the same team heard this, they all nodded, and there was a hint of perseverance on their faces. Although the outcome has been decided, the time has not come, as the pride of Taicheng Middle School, they must also persevere to the end and cannot surrender halfway.

For the sake of the fragmented pride in their hearts, they picked up the pen in their hands again, and the speed of calculation seemed to have increased a little.

The people around saw the victory and defeat, but Taicheng Middle School did not give up their efforts and couldn't help but sigh secretly.

Instead, the middle-aged man looked at a few students in the Taicheng group, and his face showed approval.

It is no wonder that Taicheng Middle School can be a famous middle school in Jiang Province, which is the attitude of students who do not give up, which can be seen one or two!

Five minutes, and it passed quickly.

"The time has come!" said the middle-aged Dean Miao's serious voice.

Several people from Taicheng Middle School heard the voice, put down their pens, and their faces were slightly unwilling. Although the solution of the quadratic equation has been solved, the difficulty value has risen dozens of times in the geometry problem, which is simply beyond the sky! In five minutes, for a full five minutes, they are completely standing still, without making any progress!

The boy leader of the Taicheng group showed the problem to the middle-aged man, and then saw the middle-aged man shaking his head with a trace of unwillingness on his face.

They lost, not only defeated, but defeated, losing to the Lincheng group by an absolute score.

"Can you show us their answers?" the boy leader pleaded. The people in the Taicheng group also looked at the middle-aged man with pleading eyes.

They want to know where they are defeated!

When the middle-aged man heard this, he smiled slightly, and then handed him the paper that Li Jie handed over.

They took the first sheet of paper and saw a slightly sleek font. Because I've seen it before, and it's deeply influential, I know that this is the font of a group of boys in the city.

Then they immediately saw the conversion formula of the font, looked at each other, and suddenly felt how could they be so stupid! No wonder when they did the second step before, they felt that it was difficult to move forward. It turned out that they were wrong in the first place. The two problems should be solved independently, and then the correct solution is to transform and connect.

At this time, the middle-aged man also solemnly announced: "Lincheng wins a group, accumulates four points, and advances to the top 16!" Then he turned his gaze to Li Jie and the others, and said with a smile: "Congratulations!"

"Hee, we've advanced to the top 16!" Mu Qingqing grinned.

When Li Jie and the others heard this, they also smiled.

Although I know that there is no problem with the promotion, I am also relieved now.

Successfully advanced to the round of 16!!

Before leaving.

Li Jie and the others found a group of people from Taicheng walking towards them, and they were slightly curious to a group of people from Taicheng. (To be continued.) )
