分式方程的增根与无解是分式方程中常见的两个概念,同学们在学习分式方程后,常常会对这两个概念混淆不清,认为分式方程无解和分式方程有增根是同一回事,事实上并非如此,分式方程有增根,指的是解分式方程时,在把分式方程转化为整式方程的变形过程中,方程的两边都乘了一个可能使分母为零的整式, The incremental and non-solution of fractional equations are two common concepts in fractional equations. After studying the fractional equations, the students often confused the two concepts, and considered the fractional equations to have no solutions and fractional equations. Scaling up is the same thing, but in fact it is not. When the fractional equation is rooted, it means that when the fractional equation is solved, in the process of transforming the fractional equation into the integral equation, both sides of the equation are multiplied by one. a whole formula that may make the denominator zero,
