(x^2+xy)/(x+y)^2怎么约分?(x^2+xy)/(x+y)^2怎么约分?(x^2+xy)/(x+y)^2怎么约分?(x^2+xy)/(x+y)^2=x(x+y)/(x+y)²=x

(x^2+xy)/(x+y)^2怎么约分?
(x^2+xy)/(x+y)^2怎么约分?

(x^2+xy)/(x+y)^2怎么约分?
(x^2+xy)/(x+y)^2
=x(x+y)/(x+y)²
=x/(x+y)

原式=x(x+y)/(x+y)^2
=x/(x+y)

(x^2+xy)/(x+y)^2
=x(x+y)/(x+y)^2
=x/(x+y)

x^2-xy/xy-y^2约分 (x^2+xy)/(x+y)^2怎么约分? 约分:x²-4/xy+2y 约分:x*2+xy/x*2+2xy+y*2 x+xy/y²-1怎么约分约分x^2+xy/x^2-y^2 x的2次方-2x/2y-xy 约分约分：x^2+xy/(x+y)^2= x^2+xy/(x+y)^2如何约分急,快约分2y-xy分之x²-2x 把分式xy-y/x-2x+1约分 (x+y)y/xy^2 约分后是什么约分:9xy^2+6xyz/3x^2y 约分：（x²-4）/（xy+2y）分式约分x^3-4xy^2/-x^3-4x^2y-4xy^2 约分：2x²y-2xy²/x²-2xy+y² x^2y+xy^2/xy^3-x^3y约分 X^2-4分之X^2-2X ,X+Y分之X^3-XY^2. 约分.
