多项式因式分解是初中代数的重点内容,必须认真学好.那么,怎样才能学好因式分解呢?一、正确理解因式分解的意义正确理解因式分解的意义,是学好因式分解的基础简单地说,因式分解就是把一个多项式化成几个整式的乘积形式的一种变形,它与整式乘法是互逆的.理解因式分解概念应注意以下几点:(1)要分清什么是因式分解,什么是乘法运算. Polynomial factorization is the key content of the junior high school algebra, must be carefully studied.So, how can we learn factorization? First, a correct understanding of the meaning of factorization Correct understanding of the meaning of factorization is to learn factorial decomposition is simple To say that factorization is a polynomial into a few integer products of a form of deformation, which is inversely proportional to integer multiplication. Understanding of factorization should pay attention to the following points: (1) to distinguish what is due to Decomposition, what is multiplication.
