(2x-3y)(3x-2y)=(2x-3y)(3x-2y)=(2x-3y)(3x-2y)=原式=2x(3x-2y)-3y(3x-2y)=6x²-4xy-9xy+6y²=6x
(2x-3y)(3x-2y)=
(2x-3y)(3x-2y)=
(2x-3y)(3x-2y)=
原式=2x(3x-2y)-3y(3x-2y)
=6x²-4xy-9xy+6y²
=6x²-13xy+6y²
(2x-3y)(3x-2y)
=6x²-13xy+6y²

原式=(2x-3y)^3 + [(3x-2y)-5(x-y)][(3x-2y)^2+5(3x-2y)(x-y)+25(x-y)^2]
=(2x-3y)^3 + (3y-2x)[(3x-2y)^2+5(3x-2y)(x-y)+25(x-y)^2]
=(2y-3x)【(2y-3x)^2 - (2y-3x)[(3x-2y)^2+5(3x-2y)(x-y)+25(x-y)^2] 】
(x-y) (x-2y)+(x+2y) (x-3y)-2(x-3y) (x-4y)=
(x+y)(x-y)+(x-y)平方-(x-y)(3x-y) 其中x=-2 y=3分之一
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
(x+y)(2x-3y)=?
【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2=
已知x-y=3,求[(x+y)(x-y)-(x-y)^2+2y(x-y)]除以的值
已知3x =2y 求x/x+y+y/x-y-y²/x²-y²
x(x-y)2-(y-x)3
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
[2/3x-2/x+y(x+y/3x-x-y)]/x-y/x
化简:{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x
计算2/3x-2/x+y(x+y/3x-x-y)/x-y/x
化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
{(x+2)^2-(y-3)^2=(x+y)(x-y) {x-3y=2
(3x-y)^2+(3x+y)(3x-y),x=1,y=-2
2(x+y)-3(x-y)=3 ,4(x+y)+3(x-y)=15
(-x+2y)(2x+y)-(2x+y)(y-2x)-3xy=?因式分解
计算:y(x-y)^2+(y-x)^3=?
