Question

把下列各式分解因式:(x+y)^2-(x+y)^3要写过程哦

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?
