Answer 2

$<b>Heya mate. (^_-). Solution below.$
====================================

• x² + (1/x²) = 14

Adding 2 on both sides -

• x² + (1/x²) + 2 = 14 + 2

We can write it as -

=> x² + (1/x²) + 2 × x × 1/x = 16


• Now using identity : a² + 2ab + b² = (a +b)²

=> [x + (1/x)]² = 16

=> x + (1/x) = √16

=> x + (1/x) = 4
