因式分解是整式运算中的重要内容之一.如何学好因式分解呢?不妨从以下几方面着手.一、因式分解的意义什么是因式分解?就是把一个整式转化为几个整式积的形式.因式分解是针对整式的,不是分式或其他的代数式,这是研究对象的所在范围.那么,它研究的方向是什么呢?方向是把这个整式转化为几个整式的积的形式,就是说,把要分解的一个多项式写成几个(两个或两个以上)的 Factorization is one of the most important parts of integer computing .How to learn how to factorize it? May wish to proceed from the following aspects. First, the meaning of factorization What is factorization? Is to transform an integer into several integer products .Form decomposition is for integer, not fractional or other algebra, which is the scope of the research object. So, what is the direction of its research? The direction is the integer into several integral products Form, that is, write a polynomial to be decomposed into several (two or more)
