(x+2y)^2(x-2y)^2-2(x+2y)(x-2y),其中x=2008,y=-1(x+2y)^2(x-2y)^2-2(x+2y)(x-2y),其中x=2008,y=-1(x+2y)^2(x-2
(x+2y)^2(x-2y)^2-2(x+2y)(x-2y),其中x=2008,y=-1
(x+2y)^2(x-2y)^2-2(x+2y)(x-2y),其中x=2008,y=-1
(x+2y)^2(x-2y)^2-2(x+2y)(x-2y),其中x=2008,y=-1
(x+2y)^2(x-2y)^2-2(x+2y)(x-2y)
=(x+2y)^2(x-2y)^2-2(x+2y)(x-2y)+1-1
=[(x+2y)(x-2y)-1]^2+1
=(2006×2010-1)^2+1

x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
化简y(x+y)+(x+y)(x-y)-x^2
因式分解x(x+y)(x-y)-x(x+y)^2
(x+y)(x-y)-(x-y)^2如题 (x+y)(x-y)-(x-y)^2
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
x^2(x-y)+(y-x)
x(x-y)2-(y-x)3
【(x-y)^2+(x+y)(x-y)】除以 2x
计算:y-x分之x+y+x-y分之y-y-x分之2x-y
[(x-y)²+(x+y)(x-y)]除以2x
[(x-y)^2-(x+2y)(x-2y)]/y
[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
计算[2x^2-(x+y)(x-y)][(-x-y)(y-x)+2y^2]
