Solution

The correct option is C
(6/5)

$\frac{(2 x - 1) (x + 2) - 2 x (x - 2)}{(x - 2) (x + 2)} - \frac{x + 2 - 4 (x - 2)}{(x - 2) (x + 2)} \Rightarrow 2 x^{2} + 4 x - x - 2 - 2 x^{2} + 4 x = x + 2 - 4 x + 8 \Rightarrow 3 x + 4 x - 2 = - 3 x + 10 \Rightarrow 10 x = 12 \Rightarrow x = \frac{6}{5}$
