(x^2-y^2)(x/x-y+y^2/x^2-y^2-x-y/x+y) 【/为分数线,不是除号】
(x^2-y^2)(x/x-y+y^2/x^2-y^2-x-y/x+y) 【/为分数线,不是除号】
1、x(x-y)(x+y)-x(x+y)^2
(x-y/x+2y)³
(分数线用/代替吧)通分:1.2x/x²+y²,y/(x+y)² 2.y/2(x-y),x
(1)(x^2/x)-y-x-y
【(x-y)^2+(x+y)(x-y)】除以 2x
求因式分解(x-y)²-2(x-y)³和(x+y)(x-y)-x(x-y)
x根号x+x根号y/xy-y^2)-(x+根号xy+y/x根号x-y根号)y
[(-x-y)(-x+y)-(x+y)^2-x(y-y^2)}÷1/2y
1.((y+2x)(-2x+y)+4(x+2y)^2)/3y 2.(2(x-y)^3-8(x-y)^2(x+y)+6y(
(x-y)(x-2y)-(3x-2y)(x-3y)
x^2-y^2/x+y-4x(x-y)+y^2/2x-y,
