Question

solve Question no 14 .....

Answer 1

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

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

x × 1/x =1

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

given x² +1²/x = 83

$83 + 2 \times 1 \\ = 166$

taking square root on both sides

$x + \frac{1}{x} = +- \sqrt{166}$
