化简x^2-yz/[x^2-(y+z)x+yz]+y^2-zx/[y^2-(z+x)y+zx]+z^2-xy/[z^2-(x+y)z+xy]
化简x^2-yz/[x^2-(y+z)x+yz]+y^2-zx/[y^2-(z+x)y+zx]+z^2-xy/[z^2-(x+y)z+xy]
化简x^2-yz/[x^2-(y+z)x+yz]+y^2-zx/[y^2-(z+x)y+zx]+z^2-xy/[z^2-(x+y)z+xy]
（x^2-yz）/[x^2-(y+z)x+yz]+（y^2-zx）/[y^2-(z+x)y+zx]+（z^2-xy）/[z^2-(x+y)z+xy]=（yz-x^2）/（x-y）(z-x)+（zx-y^2）/(y-z)(x-y)]+（xy-z^2）/(z-x)(y-z)=…………/（x-y）(y-z)(z-x)=0.
化简(2x-y-z/x^2-xy-xz+yz)+(2y-x-z/y^2-xy-yz+xz)+(2x-x-y/z^2-xz-yz+xy)
