八年级上学期(人教版)学习了解分式方程,常常会遇到下列情况.例1解分式方程1/(x-5)=10/(x~2-25).(1)解在方程两边乘最简公分母(x-5)(x+5)得到整式方程,x+5=10,(2)解之得x=5.将x=5代入原方程检验,发现这时分母x-5和x~2-25的值都为0,相应的分式无意义.因此,x=5虽是整式方程x+5=10的解, The eighth grade last semester (PEP) Learning to understand the fractional equation, often encounter the following situations. Example 1 solution equation 1 / (x-5) = 10 / (x ~ 2-25). Get the integral equation by the simplest common denominator (x-5) (x + 5) on both sides of the equation, x + 5 = 10, (2) the solution of x = 5. Substitute x = 5 into the original equation test and found that The denominator x-5 and x ~ 2-25 have a value of 0 and the corresponding fraction has no meaning. Therefore, x = 5 is the solution of the integral equation x + 5 = 10,
