[(-x-y)(-x+y)-(x+y)^2-x(y-y^2)}÷1/2y
化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
[(x+y)(x-y)-(x-y)²+2y(x-y)]÷4y
[(x+2y)²-(x+y)(x-y)-7y²】÷(2y)
计算:(x-y)^7÷(y-x)^6+(-x-y)^3÷(x+y)^2
计算(x-y)^7÷(y-x)^6+9-x-y)^3÷(x+y)^2
18(x+y)^8(x-y)^7÷[3(x+y)^3(x-y)^3]^2
(x+y)-(x-y)^3÷(x-y)(x+y)×2y化简e ,
[2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
[(-2x-y)^2-(2x+y)(2x-y)]÷2y-1/2y
[(x+2y)^2-(x-y)(x+2y)-5y^2]÷(2y)
[(2x+y)-(2x+y)(2x-y)]÷2y-二分之一y
化简【(x²+y²)-(x-y)²+2y(x-y)】÷4y
计算:y×(y/x)^3÷[-(x^2)/y]^-2
(x-y/x+y)^2÷(y-x/x^2+2xy+y^2)^2
[4y(2x-y)-2x(2x-y)]÷(2x-y)
[4y(2x-y)-2x(2x-y)]÷(2x-y)怎么做
