摘要
通过多项式理论,得到了考察代数方程是否有重根的一种判别式,进而给出了求解代数方程的一种数值计算方法,实例表明该法对求解次数≤6的方程根是非常有效的.
In the present paper, a discriminant formula for multiple root of the algebraic equation is obtained by the polynomial theory, and a numerical method of solving algebra equation＇s root is given. It is sued for fmding equation＇s root of its degree ≤ 6.
