Question

分解因式,
(x+y)^2-(x+y)^3
(x-y)^2-(x-y)^3
(x-y)^2-(y-x)^3
2(x-y)-3(y-x)^2
2a(a-3)^2-6a^2(3-a)+8a(a-3)
24xy^2z^2(x+y-z)-32xyz(z-x-y)^2+8xyz^2(z-x-y)

Answer 1

（x+y+1)(x+y)^2
(1-x+y)(x-y)^2
(x-y)^2(1+x-y)
(x-y)(2-3y+3x)
2a(a-3)(a-3+3a+4a)=2a(a-3)(8a-3)
8(x+y-z)(3xy^2z^2+4xyz-xyz^2)=8xyz(x+y-z)(3yz+4-z)
