进行多项式的因式分解，一般应先考虑有没有公因式可提取，在提取了公因式以后，或者在没有公因式可提取的情况下，我们可以再根据多项式的项数来确定因式分＠的方法，一般可以分为以下几种类型．一、二项式对于二项式，首先应考虑能否应用平方差公式、立方和及立方差公式．在 The factorization of polynomials should generally be considered whether there is a public factor extractable. After the common factor has been extracted, or if there is no public factor extractable, we can determine the cause based on the number of polynomial terms. The method of fractional @ can generally be divided into the following types. 1. Binomial For the binomial formula, first consider whether the square difference formula, cubic sum, and cubic difference formula can be applied. in
