Question

Помогите пожалуйста....

Answer 1

Ответ:

$\frac{x(x - 2) + (x + 2)(x + 2)}{x { }^{2} - 4} = \frac{8}{x {}^{2} - 4 } \\ \frac{ {x}^{2} - 2x + x {}^{2} + 4 + 2x + 2x - 8}{x {}^{2} - 4 } \\ \frac{2x {}^{2} + 2x - 4 }{x {}^{2} - 4 } = 0\\ 2x {}^{2} + 2x - 4 = 0 \\ x {}^{2} + x - 2 = 0 \\ x = - 2 \\ x = 1$
