1.(xy-1)^2-(x+y-2xy)(2-x-y)2.(x+y)(x+y+2xy)+(xy-1)(xy+1)
(x^2-xy)y÷y-x/xy怎么做?
.(x+y-2)(x+y-2xy)+(xy-1)^2
[(x+y)^2-(x-y)^2]÷(1/2xy)
(xy-x²)÷(x²-2xy+y²/xy)×(x-y/x²)
x-y/x²÷x²-2xy+y²/xy*(xy-x²)
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
(x²-4y²)÷(2x+y)/xy×1/x(2y-x)(2x+y)/xy 1/x(2y-x) 都是一项
计算x²-x/x²×x/1-x和x²-4y²/x²+2xy+y²÷x+2y/x²+xy
【(1)/(x-y)+(1)/(x+y)】÷(2x)/(x²-2xy+y²)
(x+y)(x+y+2xy)+(xy+1)(xy-1)(x+y)(x-y)+4(y-1)
化简求值x-4y/2x-7xy+3y×x-2xy-3y/2x+3xy-2y÷3x-6y/4x-4xy+y,其中:x=1999,y=-1

已知x(x-1)-(x²-y)=-3,求(x²y+xy²)÷xy-2y
计算3xy[2xy-x(y-2)+x-1]
计算:(x+y/x-y)÷(xy+x^2)
计算(3x^3y-x^2y+1/2xy)÷(-1/2xy)
