化简:(x+y-4xy/x+y)*(x-y-4xy/x-y)=化简:(x+y-4xy/x+y)*(x-y-4xy/x-y)=化简:(x+y-4xy/x+y)*(x-y-4xy/x-y)=题目是不是打错
化简:(x+y-4xy/x+y)*(x-y-4xy/x-y)=
化简:(x+y-4xy/x+y)*(x-y-4xy/x-y)=
化简:(x+y-4xy/x+y)*(x-y-4xy/x-y)=
题目是不是打错了一个符号.
应该是：
（x+y-4xy/(x+y))·（x-y+4xy/(x-y)）=[(x+y)²-4xy]/(x+y)·[(x-y)²+4xy]/(x-y)
=(x-y)²/(x+y)·(x+y)²/(x-y)
=(x+y)(x-y)
=x²-y²

化简:[4xy(x-y)^-1 + (xy^-1 - x^-1y)/(x^-1 + y^-1)] / (x+y)^2
计算下面式子{x-y+[(4xy)/(x-y)]}{x-y-[(4xy)/(x-y)]}
（x-y+4xy/x-y）(x+y-4xy/x-y)
(x-y+4xy/x+y)(x+y-4xy/x+y)等于的多少? 谢谢!
化简计算:[x-y+4xy/(x-y)] * [x+y-4xy/(x+y)]
计算:[x-y+4xy/(x-y)] * [x+y-4xy/(x+y)]
计算：（x-y+4xy/x-y)(x+y-4xy/x+y)
