化简x3-x2/x2+x-2化简x3-x2/x2+x-2化简x3-x2/x2+x-2(x^3-x^2)/(x^2+x-2)=x^2(x-1)/[(x+2)(x-1)]=x^2/(x+2)=x²

化简x3-x2/x2+x-2
化简x3-x2/x2+x-2

化简x3-x2/x2+x-2
(x^3-x^2)/(x^2+x-2)=x^2(x-1)/[(x+2)(x-1)]=x^2/(x+2)

=x²/(x+2)

[x³-x²]/[x²+x-2]
=[x²(x-1)]/[(x-1)(x+2)]
=x²/(x+2)
如果满意望采纳!

x3-x2/x2+x-2
=x^2(x-1)/(x-1)*(x+2)
=x^2/(x+2)
请采纳,谢谢

原式=x^2(x-1)/(x-1)(x+2)=x^2/(x+2)

结果都很正确··哈
