Question

помогите
$frac{x}{x - 2} - frac{7}{x + 2} = frac{8}{x {}^{2} - 4}$

Answer 1

$frac{x}{x - 2} - frac{7}{x + 2} = frac{8}{ {x}^{2} - 4 } \ frac{x}{x - 2} - frac{7 }{x + 2} = frac{8 }{(x - 2)(x + 2)}$
$x(x + 2) - 7(x - 2) - 8 = \ {x}^{2} + 2x - 7x + 14 - 8 = \ {x}^{2} - 5x + 6$

Не знаю может быть так
