一元n次多项式的重根问题

On the Problem of Fold Root of a Variable Polynomial if Degree N

本文利用一元n次多项式的系数与其根的关系探讨一元n次多项式具有n，l与n－l重根的问题。

In this paper, We disscused the problem of fold root of a variable polynomial of degree non the base of relationship between its coefficient and root. So we obtained some importantresults about it. The problem of n-fold, l-fold and (n-l)-fold root of a variable poly-nomial of degree n has etirely solved.
