HEYA MATEY ...✨✌️^_^

GOOD MORNING ..✴^_^✌️✨

THERE'S YOUR ANSWER ....

$given \: x + \frac{1}{x} = 11$


THEREFORE,

$x {}^{2} + \frac{1}{x {}^{2} } = 11 {}^{2}$

$= > x {}^{2} + 2 \times x \times \frac{1}{x } \times y {}^{2} = 11 {}^{2}$

$= > x {}^{2} + \frac{1}{x {}^{2} } = 119$

HOPE IT HELPS YOU DEAR ..^_^
