众所周知,用常规方法解分式方程,往往都会出现增根,须通过检验将其及时排除;而对于某些特殊的分式方程,采用如下方法求解,就可避免增根的产生.现举例说明如下几种方法. As we all know, using conventional methods to solve fractional equations, rooting often occurs, which must be eliminated in time through testing. For some special fractional equations, using the following method to solve, you can avoid the root growth. The following methods.
