Answer 2

Step-by-step explanation:

$\blue{\mathfrak{\underline{\huge{Answer}}}:} \\ \blue{\mathfrak{\underline{\large{Given}}}:} \\ x + \frac{1}{x} = 4 \\ \blue{\mathfrak{\underline{\large{To find}}}:}\\ {x}^{2} + \frac{1}{ {x}^{2} } = ? \\ \blue{\mathfrak{\underline{\large{Finding}}}:} \\ x + \frac{1}{x} = 4 \\ \blue{\mathfrak{\underline{\large{Square \: on \: both \: sides}}}:} \\ {(x + \frac{1}{x} )}^{2} = {(4)}^{2} \\ {x}^{2} + \frac{1}{ {x}^{2} } + 2 \times x \times \frac{1}{x} = 16 \\ {x}^{2} + \frac{1}{ {x}^{2} } + 2 = 16 \\ \boxed{{x}^{2} + \frac{1}{ {x}^{2} } = 14}$
