What to do if your mind is always blank when doing math problems 20

Don't be nervous, take your time, math is all about logical thinking skills, the more nervous you are, the less you know how to do it! Calm down and sort out the problem step by step!

Adjust your mentality, believe in yourself, review the knowledge points before the exam, study hard, do your homework well, and believe that if you succeed once, you will get better and better in the future.

I'm like that sometimes, and sometimes I'm in this situation, and I'm doing my homework in other subjects first, or going out to relax and relax. If you encounter this situation in the exam, you can seriously do the equation and bring your thinking into it. Hope it helps.

If you are too nervous and anxious to study, if you can't learn, you can stop learning to do anything else and calm yourself down.

If you can, try to look at the book, because I am also a student, and I often encounter such problems, and I may summarize some experience, and I can recall what the teacher said about this type of topic.

In this case, the teacher can also understand, but very passive, in fact, there is no mastery at all, it belongs to the floating type, assuming that the teacher deliberately talks about the wrong estimate of the topic can not be seen, in your case, if you want to improve your grades in the short term, the better way is to put down the problem, do particularly simple problems, find the law, establish your own set of problem-solving concepts, methods, read through the textbook, remember the basic formulas and theorems, increase in layers, can not be in one step.

Mathematics is a favorite subject for many people, because as long as you understand the ideas, it is easy to get a full score, but the same is very worrying for some people, and there are many people who take the test with twenty or thirty points. Many students have this feeling when they do math problems, that is, when they face an exercise, they can understand when they look at the answers, but when they do it themselves, they are blank, and they don't know where to start. In fact, the answer we look at is not our own solution idea, but someone else's, you read it does not mean that you have learned, so I still don't understand.

If you want to change this situation, you can't just look at the answers, you must do it again to see if you can do it from scratch, and only after you have really thought about and understood the questions will be impressive. If you just look at the answer and think you can see it, when you do it again, you will find that you still can't, and the impression is very vague. <>

Secondly, we should find the same type of exercises to practice, there are so many mathematical knowledge points, the exercises are extended through the knowledge points, it can be said that everything is the same, as long as the same type of questions are understood, then this knowledge point can be more consolidated and steadfast, and when it is encountered in the future, it can be made more fresh and clear. <>

We have to develop the habit of thinking by ourselves to do math problems, the way of thinking is very important, why some people can get a full score if they don't listen to the lecture in class, and some people only pass the school, people understand it thoroughly, they can deal with any problem, they will only do this, and they will not change the topic, and the grades will not go up. You must first analyze how to do it, think about it, and calculate the results, if you don't know how to look at the answers to each question, you won't be able to learn at all. <>

Mathematics you say it's difficult for people to get a full score, you say it's easy for some people to only rely on = two or three points, the key is their own learning ability, only after they really understand can they improve their mathematics scores.

At this time, you must be diligent in practicing, mainly because you don't have a definite way of thinking, and your logical ability is relatively poor, so you should do more exercises, practice makes perfect.

First of all, you must listen carefully when you are in class, and if you have questions that you don't know, you must ask the teacher, and don't pretend to understand. And you should also do more practice problems, but also master more knowledge about textbooks, and when doing math problems, you must read the questions clearly, you must take your time, and don't be too nervous.

You can do more questions in your life, so that your mind will not be blank, and it may be caused by being too nervous.

Now most of the exams are basic questions, review the basic content well, you can go to high school, and your intelligence will be good. Review the basics well and do the basic questions well. Don't put too much pressure on yourself during the exam, and don't be afraid.

Don't worry, many people have survived like you, no matter what, you will have a future, whether you are worried or afraid, you have to go on, then do your best, relax your mind, so that you can get the best results. Believe me, only those who didn't do their best will regret it when they look back in the future, as long as you do your best (because you are a student now), you will be able to follow the path that suits you best, and you will not regret it. Calm down and do what you have to do.

The questions you used to do are now gone, you may not have understood the essence of these questions at the time, and you may not have the test points to summarize the questions.

It is recommended that you make a list of knowledge points and repeatedly use these test points to practice on the practice questions several times a day. Use it once a day, and if something is familiar, cross it off the list. There is also a list that you need to copy by hand, because the knowledge of junior high school mathematics is relatively fixed, repeat it a few times and believe that you can succeed, come on!

In the exam room, self-confidence is very important. And your self-confidence** your solid basic knowledge system, solid knowledge system, in the examination room you are a dark horse.

（3x+

15x²+30x²+168x-111=0

Using the formula method x=(-b root number b -4ac) 2a solution to x1=root number 14904 60

x2 = root number 14904 60

I'm a teacher, thank you for adopting.

Simplification obtains (x+, x squared+, using the universal root formula, x=[-b+ - root number(b squared-4ac] 2a, there is a problem to get b=, c=, a=1, find x=[root number.

y=(x-b/2)^2+1-b^2/4

Related to b is the axis of symmetry of the function x=b2 and the minimum f(b2)=1-b2 4

When b moves from -1 to 1, x=b 2 moves from left to right, and the minimum value 1-b 2 4 is from 3 4 to 1 to 3 4, that is, first up and then down

y= x 2 +x+1 minimum x= -1 2 y=3 4

y=x^2 +1 x=0 y=1

y=x^2 -x+1 x=1/2 y=3/4

They are all binary one-time functions with the opening upward, and they all look at the three minimum values above the x-axis and the case of x, and they get c

c。From the function, it can be seen that the parabolic opening is upward, the central axis is x=b 2, and the top line is y=1—b2 4

A simple way is to take a number, that is, take a few representative values and substitute them into the function, and draw a graph to know.

Also, the analysis is that the central axis of b from -1 to 1 must move to the right, so directly exclude the option of moving to the left, leaving c and d.

Then analyze the lowest point, y=1-b square 4, which must be very simple.

Let's bring in the equations with b=-1 and 1 respectively, and you can see it soon after drawing a diagram.
