因式分解:3m(x-y)^3+27m^3(y-x)因式分解:3m(x-y)^3+27m^3(y-x)因式分解:3m(x-y)^3+27m^3(y-x)3m(x-y)^3+27m^3(y-x)=3m(x

因式分解:3m(x-y)^3+27m^3(y-x)
因式分解:3m(x-y)^3+27m^3(y-x)

因式分解:3m(x-y)^3+27m^3(y-x)
3m(x-y)^3+27m^3(y-x)
=3m(x-y)^3-27m^3(x-y)
=3m(x-y)[(x-y)^2-9m^2]
=3m(x-y)(x-y+3m)(x-y-3m)

3m(x-y)^3+27m^3(y-x)
=3m(x-y)((x-y)²-9m²)
=3m(x-y)(x-y+3m)(x-y-3m)
