3（x-1)³y-（1-x）³zm(x-y)²-x+yx²(x+y)(y-x)-xy(x+y)(x-y)因式分解3（x-1)³y-（1-x）³
3（x-1)³y-（1-x）³z m(x-y)²-x+y x²(x+y)(y-x)-xy(x+y)(x-y) 因式分解
3（x-1)³y-（1-x）³z m(x-y)²-x+y x²(x+y)(y-x)-xy(x+y)(x-y) 因式分解
3（x-1)³y-（1-x）³z m(x-y)²-x+y x²(x+y)(y-x)-xy(x+y)(x-y) 因式分解
3个式子吧?
3（x-1)³y-（1-x）³z
=3（x-1)³y+（x-1）³z
=(x-1)³(3y+z)
(2)
m(x-y)²-x+y
=m(x-y)²-(x-y)
=(x-y)[m(x-y)-1]
=(x-y)(mx-my-1)
(3)
x²(x+y)(y-x)-xy(x+y)(x-y)
=x²(x+y)(y-x)+xy(x+y)(y-x)
=x(x+y)(y-x)(x+y)
=x(x+y)²(y-x)
