Question

Алгебра 8 класс. Помогите пожалуйста.

Answer 1

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