分解因式:2m^3 - 8m (x+2)(x+4)+ x^2 -4 4(x-y)^2 - 2(y-x)^3 x^2 (y^2 - 1)+2x(y^2 - 1)+(y^2 - 1)
分解因式:
2m^3 - 8m
(x+2)(x+4)+ x^2 -4
4(x-y)^2 - 2(y-x)^3
x^2 (y^2 - 1)+2x(y^2 - 1)+(y^2 - 1)

分解因式:2m^3 - 8m (x+2)(x+4)+ x^2 -4 4(x-y)^2 - 2(y-x)^3 x^2 (y^2 - 1)+2x(y^2 - 1)+(y^2 - 1)
1.2m^3 - 8m =2m(m^2-4)=2m(m-2)(m+2)
2.(x+2)(x+4)+ x^2 -4
=(x+2)(x+4)+(x-2)(x+2)
=(x+2)(2x+2)=2(x+2)(x+1)
3.4(x-y)^2 - 2(y-x)^3 =
4(x-y)^2 +2(x-y)^3=
(x-y)^2(4+2x-2y)
4.x^2 (y^2 - 1)+2x(y^2 - 1)+(y^2 - 1)=
(y^2 - 1)(x^2+2x+1)=(y^2 - 1)(x+1)^2
