分式方程的增根与无解是分式方程中常见的、易混淆的两个概念.每当学习分式方程后,学生们完成关于分式方程无解和有增根的题是普遍出错,究其原因,是学生对这两个概念没有彻底理解、掌握.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,分式方程的两边都乘了整式,这个整式通常是各分母的最简公分母,这样解出的方程的解(或
The rooting and non-solution of fractional equations are two common and easily confused concepts in fractional equations. Whenever you learn the fractional equation, the students complete the common and error-free problem about the fractional equation , The reason is that students do not have a thorough understanding of these two concepts to master.Fractional equation has root, refers to the solution of fractional equation, the fractional equation into an integral equation of the deformation process, fractional Both sides of the equation are multiplied by an integer, which is usually the simplest common denominator of each denominator. The solution to this equation (or
