分式方程有增根,也可以解释为分式方程无解,是解分式方程有关问题时经常会遇到的一种情况.在解分式方程的过程中往往都是按一般的分式方程求解步骤,去分母,移项、合并同类项,由此而导致一些典型性错误的出现,下面简单介绍几种常见错误及出现错误的原因:易错点一、解方程时检验不仔细,增根没舍去 Fractional equation rooted, can also be interpreted as fractional equation without solution, is a solution to the problems associated with fractional equation often encountered in the process of solving the fractional equation are often based on the general fractional The process of solving equations, denominator, shift, merging similar items, which led to some typical mistakes, the following brief introduction to several common mistakes and the reasons for the error: error-prone one, solving the equation when the test is not careful, Increased root did not go home
