1 x²y-3xy²
2 2x(2x-y)+y(y-2x)
3 -6x(m-2n)+12(2n-m)
4 3(y-x)²-(x-y)³
5 4a²-36
6 (x-2y)²-x²
7 4x³y+4x²y²+xy³
8 (x+y)²-2m(x+y)+m²
9 x²-9x+18
10 -8x²-10x-3
答
1.xy(x-3y)2.(2x-y)(2x-y)=(2x-y)^23.-6(m-2n)(x+2)4.3(x-y)^2-(x-y)^3=(x-y)^2(3-(x-y))=(x-y)(3-x+y)=(x-y)(y-x+3)5.4(a^2-9)=4(a-3)(a+3)6.(x-2y-x)(x-2y+x)=-2y(2x-2y)=-4y(x-y)7.4x^3y+4x^2y^2+xy^3=xy(4x^2+4x...
