通分:(1)x/(x^2+2xy+y^2)与y/(x+y)(2)(x+4)/(x^2+4x)与(x-5)/x(x-5)-2(x-5)通分:(1)x/(x^2+2xy+y^2)与y/(x+y)(2)(x

通分:(1)x/(x^2+2xy+y^2)与y/(x+y) (2)(x+4)/(x^2+4x)与(x-5)/x(x-5)-2(x-5)
通分:(1)x/(x^2+2xy+y^2)与y/(x+y) (2)(x+4)/(x^2+4x)与(x-5)/x(x-5)-2(x-5)

通分:(1)x/(x^2+2xy+y^2)与y/(x+y) (2)(x+4)/(x^2+4x)与(x-5)/x(x-5)-2(x-5)
(1)x/(x^2+2xy+y^2)与y/(x+y)
x/(x+y)²与y(x+y)/(x+y)²
(2)(x+4)/(x^2+4x)与(x-5)/x(x-5)-2(x-5)
(x+4)/(x^2+4x)=(x+4)/x(x+4)=1/x
(x-5)/x(x-5)-2(x-5)=(x-5)/(x-5)(x-2)=1/(x-2)
通分后是：(x-2)/x(x-2)与x/x(x-2)

分式的通分：2xy/(x+y)^2与x/(x^2+y^2)分式通分, ,x平方-2xy+y平方分之x 通分 2xy/(x+y)(x+y)与x/(x+y)(x-y)怎么通分 1/xy-y∧2,x+y/x∧2-y∧2通分, 通分x+y/x平方-y平方,2xy/x平方-xy 通分 1/3xy³,1/2x²y,1/9x³y 通分x-y/2x+2y与xy/(x+y）的2次方通分x-y/2x+2y与xy/(x+y)2 a/x-y,b/3y-3x,c/x^2-2xy+y^2通分通分 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 (x-y)/(2x+2y)与(xy)/（x+y）²通分要过程 2x+2y/x-y与(x+y)²/xy 怎么通分 2x+2y/x-y与（x²+y²）/xy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 2xy/(x+y)^2与x/x^2-y^2分式通分急急急急!
