Answer 1

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

$(\frac{2(x + 2)}{(x - 2)(x + 2)} + \frac{x(x - 2)}{(x - 2)(x + 2)} ) \times \frac{x(x - 2) + (x - 2)}{(x - 2)(x + 2)}$

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

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

$\frac{(x - 2)(x + 2)(x + 1)}{(x + 2)(x - 2)(x + 2)} = \frac{(x + 1)}{(x + 2)}$
