导数在因式分解中的应用

Applying derivative to factorization

分解因式方法灵活多变 ,技巧性强 ,尤其是多元项式的因式分解更为复杂。目前 ,还没有一种统一的方法可行。本文给出了多元多项式能因式分解的必要条件和操作步骤 。

The way of fractorization is flexible and skillful,especially the factorization of muitivariate polynormial is more complex. At present,there is no unified way yet. This paper gives the necessary condition and operating steps that help multivariate polynomial to be factorized,which make it simple in multivariate polynomial being factorized.
