Question

2x 2y/x2 y2 . x2 +2xy+y2/4+x4y​

Answer 1

Resposta:

               \frac{2x-2y}{x^2-y^2} .x^2+ \frac{2xy+y^2}{4x+4y}  \\  \\ = \frac{2(x-y)}{(x+y)(x-y)} .x^2 + \frac{y(2x+y)}{4(x+y)}  \\  \\ = \frac{2x^2}{x+y} + \frac{y(2x+y)}{4(x+y)}  \\  \\  =\frac{4.2x^2+y(2x+y)}{4(x+y)}

 

              = \frac{8x^2+2xy+y^2}{4(x+y)}
