5x/(x+3)(x+2)+(2x-5)/(x-4)(x+3)=(7x-70)/(x+2)(x+4)
问题描述:
5x/(x+3)(x+2)+(2x-5)/(x-4)(x+3)=(7x-70)/(x+2)(x+4)
求求大家帮个忙,怎么接着道方程啊!
答
你题目 校对一下!如果是5x/(x+3)(x+2)+(2x-5)/(x-4)(x+3)=(7x-70)/(x+2)(x-4)那么1/[X+3]*5X/[X+2]+1/[X+3]*[2X-5]/[X-4]=7x-70)/(x+2)(x+4) 1/[X+3]*{5X/[X+2]+[2X-5]/[X-4]}=7x-70)/(x+2)(x+4) 1/[X+3]*{5X*...
