我们知道,在解分式方程时常会产生增根.分式方程的增根,既是变形后所得整式方程的根,又是使原分式方程各分式的最简公分母为零的未知数的值.下面举例说明分式方程的增根在解题中的应用. We know that increasing roots in solving fractional equations often results in increasing the root of the fractional equation, which is both the root of the resulting integer equation after the deformation and the unknown that makes the simplest common denominator of each fraction of the original fractional equation zero. Values. The following example illustrates the application of the rooting of fractional equations in problem solving.
