解分式方程的基本思路是利用等式的性质将分式方程转化为整式方程,再解这个整式方程,还要验根,以舍去增根.进而写出原方程的解.而在实际求解时,由于步骤把握不到位,常会出现这样或那样的错误.下面举例加以说明,供同学们参考.一、去分母时出现错误.去分母时,只将含有分母的项乘最简公分母,不含分母的整式的项漏乘,从而造成错误.例题1解方程:(2-x)/(x-3)=1-1/(3-x)
The basic idea of the solution of fractional equation is to use the nature of the equation to convert the fractional equation into an integral equation, and then solve the integral equation, but also test the root, to give up the roots, and then write the original equation of the solution. Solve, because the steps do not grasp the position, often appear this or that error .Examples to illustrate, for the students to reference .In the denominator error when going to the denominator, only the denominator of the product by the most common denominator (2-x) / (x-3) = 1-1 / (3-x) Equation 1 Solve equation:
