Answer 2

Step-by-step explanation:

$x = 2 - \sqrt{3 = \frac{1}{?x = 1 \frac{2 - \sqrt{3} = 2 + \sqrt{3 \\ \\ {x}^{2} + 1 \frac{x {2}^{2} }}2 \: \: - 2 = {2 - \sqrt{3 + 2 + \sqrt{3} {2}^{2} {2 - 2 = 14} \\ \\ x {2}^{2} - \frac{1}{?x {2}^{2} } = {x - \frac{1}{?x} } \: {x + \frac{1}{x?} = 4 \times - 2 \sqrt{3} = - 8 \sqrt{3}$
