Question

simplifique
(x^2/x^2-4) - (x+1/x+2)​

Answer 1

Resposta:

1 / x - 2

Explicação passo-a-passo:

$\frac{x^{2} }{x^{2} -4} -\frac{x+1}{x+2}\\\\\frac{x^{2} }{(x-2).(x+2)} -\frac{x+1}{x+2}\\\\\frac{x^{2} -(x+1).(x-2)}{{(x-2).(x+2)}}\\\\\frac{x^{2} -(x^{2} -x-2)}{(x-2).(x+2)}\\\\\frac{(x+2)}{(x-2).(x+2)}\\\\\frac{1}{x+2}$
