摘　　要：利用方程代数解的通用形式的思路,结合根与系数的关系,根据多项式的置换和对称多项式的思想,推导出了三次方程的代数解.In this paper,the algebraic solution of cubic equation is deduced by using the idea of general form of algebraic solution of equation and the relation between root and coefficient,according to the idea of polynomial permutation and symmetric polynomial.

关 键 词：三次方程 代数解 置换 组合
