在历届全国各地的中考试题中，经常见到（其中a、b、c都是常数，a，b不用时为零，f（x）是关于x的式于）的方程．这类方程一般都是分式方程和无理方程．如果按照解分式方程和无理方程的一般步骤去解就相当复杂，甚至解不出来，本文举例介绍这类方程的五种特殊解法，供读者学习 In the middle school examination questions all over the country, it is often seen that (a, b, c are constants, a, b is not zero, and f(x) is an equation about x). This type of equation is generally a fractional equation and an irrational equation. If we follow the general steps of solving fractional equations and irrational equations to solve the solution is quite complicated, even if the solution does not come out, this article gives an example of five special solutions of such equations for readers to learn
