Question

Алгебра 8 класс. Помогите пожалуйста.

Answer 1

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