数学化简计算:(x+y)^2/xy-(x-y)^2/xy

来源：学生作业帮编辑：作业帮分类：数学作业时间：2024/05/12 06:38:36

(x+y)^2/xy-(x-y)^2/xy
=【(x+y)^2-(x-y)^2】/xy
=（x²+y²+2xy-x²-y²+2xy）/xy
=4xy/xy
=4

数学化简计算:(x+y)^2/xy-(x-y)^2/xy （x^2+xy/x-y)/（xy/x-y)计算 x-y/xy-y^2计算计算（xy-y^2)÷x-y/xy 计算3xy[2xy-x(y-2)+x-1] 计算：3xy[2xy-x（y-2）+x] 计算：x²+2xy+y²/xy-y².x²-2xy+y²/xy+y&# 计算：(x+y/x-y)÷(xy+x^2) （xy-x^2)乘以(xy)/(x-y) 计算：y/(x的平方-xy)+2/(y-x)-x/(y的平方-xy) 计算：(xy-x²)×x-y/xy 谁帮我化简：[(x+y)(x-y)-(x+y)^2-2y(x-y)-2xy]÷xy
