Answer 2

$x + \frac{1}{x} = 12 \\ \\ square \: both \: sides: \\ \\ { ( x + \frac{1}{x} )}^{2} = {12}^{2} \\ \\ {x}^{2} + \frac{1}{ {x}^{2} } + 2 \times x \times \frac{1}{x} = 144$

${x}^{2} + \frac{1}{ {x}^{2} } + 2 = 144 \\ \\ {x}^{2} + \frac{1}{ {x}^{2} } = 144 - 2 \\ \\ {x}^{2} + \frac{1}{ {x}^{2} } = 142$
