（x-y+4xy/x-y）(x+y-4xy/x-y)

（x-y+4xy/x-y）(x+y-4xy/x-y) 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)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)] 化简[x-y+4xy/(x-y)][x+y-4xy/(x-y)] 计算：（x-y+4xy/x-y)(x+y-4xy/x+y) (x一y+4xy/x-y)(x+y-4xy/x+y) 化简:(x+y-4xy/x+y)*(x-y-4xy/x-y)= (x-y+(4xy/x-y))(x+y-(4xy/x+y)) 分式计算 因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y) 求（x+y)^-4xy(x+y）的因式分解 已知x²+y²-8x+6y+25=0,求（x-y+4xy/x-y）（x+y-4xy/x+y） (x²-4y²)÷(2x+y)/xy×1/x(2y-x）(2x+y)/xy 1/x(2y-x） 都是一项 计算:2xy/(x+y)².(x+y)/4y 怎么化简（x-y+4xy/x-y）（x+y-4xy/x+y）（/是分数线） （x-y+4xy除以x-y）（x+y-4xy除以x+y）的解 （x-y+x-y分之4xy）(x+y-x+y分之4xy)的结果等于几啊?
