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)

几道因式分解..4ab(a+b)^2-6a^2b(a+b)(x+y)^2(x-y)+(x+y)(x-y)^22a(a-3)²-6a²(3-a)+8a(a-3)24xy²z²(x+y-z)-32xyz(z-x-y)²+8a(a-3)
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)(1-2a)
24xy²z²(x+y-z)-32xyz(z-x-y)²
=24xy²z²(x+y-z)+32xyz(x+y-z)²
=8xyz(x+y-z)[3yz+4(x+y-z)]
=8xyz(x+y-z)(4x+4y-4z+3yz)

2ab(a+b)(2b-a)
2x(x+Y)(x-y)
2a(a-3)(4a+1)

(a+b)(4ab(a+b)-2(3a^2b))=2ab(a+b)(b-a)
(x+y)(x-y)((x+y)+(x-y)=(x+y)(x-y)(2x)=2x(x+y)(x-y)
2a(a-3)(a-3+3a+4)=2a(a-3)(4a+1)
24xy²z²(x+y-z)-32xyz(z-x-y)²+8a(a-3) (确认有+8a(a-3)?)
24xy²z²(x+y-z)+32xyz(x+y-z)^2=8xyz(3yz-4(x+y-z))
