通分x-y/2x+2y与xy/(x+y）的2次方通分x-y/2x+2y与xy/(x+y）的2次方通分x-y/2x+2y与xy/(x+y）的2次方（x-y)/(2x+2y)=(x-y)/2(x+y)=(

通分x-y/2x+2y与xy/(x+y）的2次方
通分x-y/2x+2y与xy/(x+y）的2次方

通分x-y/2x+2y与xy/(x+y）的2次方
（x-y)/(2x+2y)
=(x-y)/2(x+y)
=(x-y)(x+y)/2(x+y)^2
xy/(x+y)^2
=2xy/2(x+y)^2
x - y/2x + 2y
=(x^2-y+4xy)/2x
=(x^2-y+4xy)(x+y)^2/2x(x+y)^2
xy/(x+y)^2
=2x^2y/2x(x+y)^2

=(x-y)/2(x+y)=(x-y)(x+y)/2(x+y) 2;=(x 2;-y 2;)/2(x+y) 2; xy/(x+y) 2;=2xy/2(x+y) 2; x-y/2x+2y 与 xy/(x

x^2-y^2/2(x+y)^2,2xy/2(x+y)^2

2xy/(x+y)(x+y)与x/(x+y)(x-y)怎么通分通分x-y/2x+2y与xy/(x+y）的2次方 (x-y)/(2x+2y)与(xy)/（x+y）²通分要过程 2x+2y/x-y与（x²+y²）/xy通分分式的通分：2xy/(x+y)^2与x/(x^2+y^2)分式通分, 通分x-y/2x+2y与xy/(x+y)2 通分 2X+2Y分之X-Y与(X+Y)²分之XY 通分 x-y/2x+2y 与 xy/(x+y)² 的 2x+2y/x-y与(x+y)²/xy 怎么通分一道数学通分题x-y/2x+2y与xy/(x+y)² 有谁知道数学通分X-Y/2X+2Y与XY/(X+Y)怎么做? 通分x-y/3x+3y与2xy/(x+y)^2 x/xy-y²与y/x²-xy 通分 “2x+2y分之x-y 与（x+y）的平方分之xy” 这道题怎么通分? 2xy/(x+y)^2与x/x^2-y^2分式通分急急急急! 2xy/(x+y)^2与x/(x^2+y^2)分式通分 x/x^2-y^2与2y/x^2+xy 通分一道数学通分题2xy/(x+y)²与x/x²-y²
