$\bf x + \frac{1}{x} = 20 \\ \\ \bf x + 1 = 20x \\ \bf 1 = 20x - x \\ \bf 19x = 1 \\ \bf x = \blue{ \underline{ \boxed{ \bf \: \: \frac{1}{19} \: \: }}}$

$\bf when \: x = \frac{1}{19} \: we \: get : \\ \\ \bf {x}^{2} + \frac{1}{ {x}^{2} } \\ \\ \bf = \cancel{(\frac{1}{19} )^{2}} + \frac{1}{ \cancel{ (\frac{1}{19})^{2} } } \\ \bf = \blue{ \underline{ \boxed{ \bf \: 1 \: }}}$
