The secret to quickly and concisely solving question number 9 (solving a system of equations) in the national high school math exam; even if you don't get full 1 point, you can still get 0.5 - 0.75 points.

Specific instructions on how to solve the most difficult questions in the Math exam are as follows:

1, Apply the square method on both sides

Squaring both sides has long been considered a "childish" method, however, with the calculators that candidates are allowed to bring into the exam room, this is the main method. In addition, to find the result, candidates also need to apply the Viet-et converse theorem - an old knowledge that many candidates have forgotten. According to Mr. Chi, in the Math exam of the Ministry of Education and Training in recent years, candidates can apply the method of squaring both sides to find the result...

2, Not always applicable

Although it is a simple and quick method to help students solve question 9 in the exam, it can be applied to replace many other methods. However, it is not certain that you can always apply this method. Therefore, students must be especially alert to recognize when to apply it. Moreover, the most important thing when using this method is to be careful, just one mistake in the minus sign will cause you to fail.

3, Other methods to solve systems of equations

In addition to the method of squaring both sides as mentioned above, to solve the system of equations, candidates can also apply the common factor group method, the conjugate method, the characteristic function method; and the evaluation method. In particular, the conjugate method is also a "strong" method that candidates need to learn carefully to solve question 9 in the exam.

4. How to solve a fourth degree equation with two "not beautiful" solutions

Regarding the national high school exam, Mr. Chi affirmed that usually the result of a system of equations is always a "nice" number. It is very rare for the result to be an odd number, if it does, it only appears in the gifted student exam, but never in the national high school exam. So candidates do not need to worry!

Listen carefully to Nguyen Quoc Chi's sharing, surely you will not feel sweaty when facing question 9 in the national high school math exam anymore! Getting a full 9 is not too difficult, right?
