解无理方程是初中数学中比较重要的内容。教材上介绍的平方法和换元法,遇有某些特殊结构的无理方程,解题过程比较繁琐。根据方程的结构特征采用恰当、灵活的解题方法,会使解题过程简捷。本文将通过例题介绍几种解无理方程的特殊方法。 Solving irrational equations is an important content of junior high school mathematics. The flat method and the substitution method introduced in the teaching materials encounter irrational equations with certain special structures and the problem-solving process is relatively tedious. According to the structural features of the equations, adopting appropriate and flexible problem solving methods will make the problem solving process simple and straightforward. This article will introduce some special methods for solving irrational equations through examples.
