因式分解!急!很简单的
1.(2x-3y)(x+y)
2.-2x(x^2+3x-1)
3.y^2-(3/4)y+____=(y-___)^2
4.(x+y+z)(x-y-z)=( )^2-( )^2=_________
5.(1/2)xy^2+2x^2=( )(y^2+4x)
6.2x^3-32x
7.a^2*b^2+4-4ab
急!九点关闭问题!答得快,好的会加分

1.2X^2-XY-3Y^2
2.12X^3-6X^2+2X
3.y^2-(3/4)y+__9/64__=(y-__3/8_)^2
4.(x+y+z)(x-y-z)=( X )^2-( Y+Z )^2=X^2-Y^2-2YZ-Z^2
5.(1/2)xy^2+2x^2=( X/2 )(y^2+4x)
6.2X(X+4)(X-4)
7.(ab-2)^2
我就看你给不给分
