几道因式分解..
4ab(a+b)^2-6a^2b(a+b)
(x+y)^2(x-y)+(x+y)(x-y)^2
2a(a-3)²-6a²(3-a)+8a(a-3)
24xy²z²(x+y-z)-32xyz(z-x-y)²+8a(a-3)
答
4ab(a+b)^2-6a^2b(a+b) =2ab(a+b)[2(a+b)-3a]=2ab(a+b)(2b-a)(x+y)^2(x-y)+(x+y)(x-y)^2 =(x+y)(x-y)[(x+y)+(x-y)]=2a(x+y)(x-y)2a(a-3)²-6a²(3-a)+8a(a-3) =2a(a-3)[(a-3)-3a+4]=2a(a-3)(-2a+1)=2a(a-3)(...
