【x²+xy/（x-y）】/【xy/（x-y）】
=【x²（x-y）/（x-y）+xy/（x-y）】/【xy/（x-y）】
={【x²（x-y）+xy】/（x-y）}/【xy/（x-y）】
=【x²（x-y）+xy】/xy
=【x（x-y)】/y+1
=（x²-xy）/y+1
=x²/y-x+1

（x^2+xy/x-y)/（xy/x-y)计算计算：(xy-x²)×x-y/xy x-y/xy-y^2计算计算3xy[2xy-x(y-2)+x-1] 计算：3xy[2xy-x（y-2）+x] 计算（xy-y^2)÷x-y/xy 计算：(x+y/x-y)÷(xy+x^2) （xy-x^2)乘以(xy)/(x-y) 计算：x²+2xy+y²/xy-y².x²-2xy+y²/xy+y&# 计算：y/(x的平方-xy)+2/(y-x)-x/(y的平方-xy) 计算:4xy-(x+y)^2/xy(x+y)(x-y)÷x^2+xy-2y^2/x^2y+2xy^2 计算(x-y)(x^2+xy+y^2)得
