化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
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
(x-y)(x-y)2(y-x) (x+2y-?)(x-2y+?)
[(-x-y)(-x+y)-(x+y)^2-x(y-y^2)}÷1/2y
[(x+y)(x-y)-(x-y)²+2y(x-y)]÷4y
因式分解x(x+y)(x-y)-x(x+y)^2
(x-y/x+y)^2÷(y-x/x^2+2xy+y^2)^2
【(2x-y)(2x+y)+y(y-6x)】÷2x
计算:[(x+y)³-2(x+y)²-4(x+y)]÷(x+y)
(x+y)(x-y)-(x-y)^2如题 (x+y)(x-y)-(x-y)^2
[(x+2y)²-(x+y)(x-y)-7y²】÷(2y)
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
1/2x-(x+y/2x -x-y)÷(x+y)
(x-2y)(x+y)+(x+y)计算
计算:(x-y)^2-(x+y)(x-y)
2(x-y)²-3(x-y)(-y-x)
[(x+y)(x-y)-(x-y)²+2y(x-y)]÷(-2y)
