Decomposition of a polynomial into the product of several simplest algebraic expressions is called decomposition of this polynomial or decomposition.

Improve the common factor: ma+mb+mc = m(a+b+c).

1, the coefficient of the common factor is a polynomial? The greatest common divisor of coefficients.

2. Are letters included in polynomials? The same letters.

3. Take the smallest index of the same letter, that is? Minimum power

General steps of factorization for solving quadratic equation with one variable;

1. Change the right side of the equation to (0).

Secondly, the left side of the equation is decomposed into the product of two factors.

3. Let each linear equation be (0) to get two linear equations.

Fourth, solving two linear equations is to find the solution of quadratic equations.
