Given Equation is x + (1/x) = 3.
On squaring both sides, we get
⇒ (x + 1/x)² = (3)²
⇒ x² + 1/x² + 2 * x * 1/x = 9
⇒ x² + 1/x² + 2 = 9
⇒ x² + 1/x² = 9 - 2
⇒ x² + 1/x² = 7.
Hope it helps!

Answer :
The value of x² + 1 / x² = 7
Step-by-step explanation :
x + 1 / x = 3
On squaring both sides ;
( x + 1 / x )² = ( 3 )²
⇒ x² + 1 / x² + 2 = 9
⇒ x² + 1 / x² = 9 - 2
⇒ x² + 1 / x² = 7
Hence, the value of x² + 1 / x² = 7
