解方程:(6x+12)/(x方+4x+4)+(x方)/(x方-4)=(x方-4)/(x方-4x+4)

解方程:(6x+12)/(x方+4x+4)+(x方)/(x方-4)=(x方-4)/(x方-4x+4)
解方程:(6x+12)/(x方+4x+4)+(x方)/(x方-4)=(x方-4)/(x方-4x+4)

解方程:(6x+12)/(x方+4x+4)+(x方)/(x方-4)=(x方-4)/(x方-4x+4)
6(x+2)/(x+2)²+x²/(x+2)(x-2)=(x+2)(x-2)/(x-2)²
6/(x+2)+x²/(x+2)(x-2)=(x+2)/(x-2)
两边乘(x+2)(x-2)
6x-12+x²=x²+4x+4
2x=16
x=8
经检验,x=8是方程的解

头疼啊

x=8
