在初中阶段,我们所学习的分式方程一般可分为以下三类:①可化为一元一次方程的分式方程:②可化为一元二次方程的分式方程:③可通过换元法化为整式方程或化为①②类方程的分式方程。学习了分式方程后,同学们知道,在解分式方程过程中去分母时,分式方程就可能产生增根,因此检验是解分式方
In the junior high school stage, the fractional equations we study can generally be divided into the following three categories: 1 Fractional equations that can be converted into a unitary first-order equation: 2 Fractional equations that can be converted into a unitary quadratic equation: 3 can be passed through the substitution method It is converted into a formula equation or a fractional equation that is converted into a 12-type equation. After learning the fractional equations, the students knew that when the denominator is used to solve the fractional equations, the fractional equations may produce rooting, so the test is to solve the fractional formulae.
