Question

simplifique a expressão :
(x+y)²-4xy------ sobre----------x²-y²

Answer 1

X²+2xy+y²-4xy/(X+Y)*(X-Y) X²-2xy+y²/(X+Y)*(X-Y) (X-Y)*(X-Y)/(X+Y)*(X-Y) (X-Y)/(X+Y)

Answer 2

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

$\frac{(x+y)-4xy}{(x-y)}$
