Answer 2

[tex]\mathfrak{\huge{Answer:-}} \\ x + \frac{1}{x} = 6 \\ Squaring \: on \: both \: the \: sides \\ {(x + \frac{1}{x} )}^{2} = {(6)}^{2} \\ {x}^{2} + \frac{1}{ {x}^{2} } + 2 = 36 \\ {x}^{2} + \frac{1}{ {x}^{2} } = 36 - 2 \\ \boxed{\boxed{\large{\bold{ {x}^{2} + \frac{1}{ {x}^{2} } = 34 }}}}[/tex]
