_______________________________
x + 1/x = ?
x² + 1/x² = 32 { Given }
_______________________________
x + 1/x = y ( Suppose )
SQUARING BOTH SIDE'S
x² + 1/x² + 2 = y²
=>
y² = 32 - 2
=>
y = √ (30) OR y = -√ ( 30)
=>
x + 1/x = √30 OR x +1/x = -√30

√34
Step-by-step explanation:
x² + 1/x² = 32
On adding 2 both sides -
⇒ x² + 1/x² + 2 = 32 + 2
⇒ (x + 1/x)² = 34
⇒ x + 1 / x = √34
