用换元法解无理方程

Methods of Substitution Used for Irrational Equation

无理方程类型很多,解的方法也是多种多样,本文根据无理方程和有理方程、无理方程和方程组之间的内在联系,介绍了用换元解一类无理方程的方法。

There are many kinds of irrational equations,and there are many way to solve the irrational equations.This paper introduced the method of substitution used for solving the irrational equations on the terms of the inner link between the rational equations and irrational equations,irrational equations and equations set.
