Common problem-solving skills in mathematics;

1, matching method.

The so-called formula is to change some items of an analytical formula into the sum of positive integer powers of one or more polynomials by using the method of constant deformation.

The method of solving mathematical problems with formulas is called matching method. Among them, the most common method is to make it completely flat.

Matching method is an important method of constant deformation in mathematics. It is widely used in factorization, simplifying roots, solving equations, proving equality and inequality, finding extreme values of functions and analytical expressions. ?

2. Factorization method.

Factorization is to transform a polynomial into the product of several algebraic expressions.

Factorization is the basis of identity deformation. As a powerful mathematical tool and method, it plays an important role in solving algebra, geometry and trigonometry problems.

There are many methods of factorization, except extracting common factors, formula, grouping decomposition and cross multiplication. Other methods introduced in the textbook are decomposition and addition, root decomposition, exchange of elements, undetermined coefficients and so on. ?

Methods of learning mathematics well

1. Mathematics, like other disciplines, has many conceptual things. The basis of learning mathematics well is to understand what the definition is about.

For example, the meaning of square, cube and absolute value in mathematics. We know that a square is the product of two identical numbers. Of course, a cube is the product of three identical numbers, and the absolute value is a value greater than or equal to 0. Knowing the true meaning of the definition, we took the first step and laid a solid foundation for the following study.

The difference between mathematics and other subjects is that there is no need to memorize, because mathematics does not test questions, but calculates, which is the biggest difference. How to practice specifically.
