The perturbed solutions to a class of algebraic equation
摘要
Abstract
Let f(x) and g(x) be two polynomials in complex number field with their orders being m and n respectively. By using direct expanding method, the approximate solutions of the perturbed algebraic equation such as f(x)+ ε g(x)=0 for m≥ n and m<n, and three formulas about two terms expansion of its roots are obtained. The m roots can be given according to the single root or pluri- root of its degenerate equation from the first two. The rest n- m roots for m<n can be given according to the third, and the relative result of [1] is generalized.关键词
