x²/xy-x/y
3x/4x+y - x-2y/4x+y
(1-y/y+x)÷x/y²-x²

求数学达人来解答
x²/xy-x/y=(1-x)/y
3x/4x+y - x-2y/4x+y=(3x-x-2y)/(4x+y)
(1-y/y+x)÷x/y²-x²=(1-y)*(y+x)(y-x)/(y+x)*x=(1-y)(y-x)/x=(y-x-y²+xy)/x

计算：(xy-x²)×x-y/xy x²/xy-x/y [-xy/(x-y)²]²×(y²-xy/x)³ x/xy-y²与y/x²-xy 通分 x-y/x²÷x²-2xy+y²/xy*（xy-x²）计算：（xy-x²）乘 x-y分之xy (xy-x²）²÷（x-y)²/xy·x-y/x² 计算 xy-1+x-y 计算：x²+2xy+y²/xy-y².x²-2xy+y²/xy+y&# (x+y)(x²-xy+y²）—xy（x+y）因式分解（xy-x^2)乘以(xy)/(x-y) 分式（x²-y²\xy）-（xy-y²\xy-x²）可化简为
