分解因式5题,今晚就要~
1.(x+y)^2-(x+y)^2
2.(x-y)^2-(x-y)^3
3.(x-y)^2-(y-x)^3
4.2(x-y)-3(y-x)^2
5.(x+y)^2(x-y)+(x+y)(x-y)^2
分解因式5题,今晚就要~1.(x+y)^2-(x+y)^22.(x-y)^2-(x-y)^33.(x-y)^2-(y-x)^34.2(x-y)-3(y-x)^25.(x+y)^2(x-y)+(x+y)(x-y)^2
1.(x+y)^2-(x+y)^2=0
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(x-y+1)
4.2(x-y)-3(y-x)^2=2(x-y)-3(x-y)²=(x-y)(2-3x+3y)
5.(x+y)^2(x-y)+(x+y)(x-y)^2=(x+y)(x-y)(x+y+x-y)=2x(x+y)(x-y)
