If x -1/7,evaluate x²+1/x²

SCORPION-xisa [38]

Answer:

$given \: x = - \frac{1}{7}$

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

$( - \frac{1}{7} ) {}^{2} + \frac{1}{ ( - \frac{1}{7} ) {}^{2} }$

$\frac{1}{49} + \frac{1}{ \frac{1}{49} }$

$\frac{1}{49} + \frac{1 \times 49}{1}$

$\frac{1}{49} + 49$

$\frac{2402}{49} \: or \: 49.02$
