Question

把下列各式分解因式:(x+y)^2-(x+y)^3要写过程哦
1:(x+y)^2-(x+y)^3=
2:(x-y)^2-(x-y)^3=
3:(x-y)^2-(y-x)^3=
4:2(x-y)-3(y-x)^2=
5:4ab(a+b)^2-6a^2b(a+b)=
6:(x+y)^2(x-y)+(x+y)(x-y)^2=
7:2a(a-3)^2-6a^2(3-a)+8a(a-3)=
8:24xy^2z^2(x+y-z)-32xyz(z-x-y)^2+8xyz^3(z-x-y)=

Answer 1

1.(x+y)^2-(x+y)^3=(x+y)^2(1+x+y)
2:(x-y)^2-(x-y)^3=(x-y)^2(1-x+y)
3:(x-y)^2-(y-x)^3=:(x-y)^2+(x-y)^3=(x-y)^2(1-x+y)
4:2(x-y)-3(y-x)^2=2(x-y)+3(x-y)^2=(x-y)(2+3x+3y)
5:太乱
6:(x+y)^2(x-y)+(x+y)(x-y)^2=(x+y)(x-y)(x+y+x-y)=2x(x+y)(x-y)
7:是不是抄错题了
8:太乱了,实在看不明白,你是初一的学生吗?
