Answer 2

Answer:

x= 11, option (b) 11 is the correct answer.

Step-by-step explanation:

We can use the identity (x + 1/x)² = x² + 1/x² + 2. Given that x² + 1/x² = 119, we can substitute the value in the identity to get (x + 1/x)² = 119 + 2 = 121. Taking the square root on both sides, we get x + 1/x = ±11.

Since we need to find the value of x + 1/x, we can eliminate the negative value as x + 1/x cannot be negative. Therefore, the value of x + 1/x is 11.

Hence, option (b) 11 is the correct answer.
