Value of x is -1/3.

Explanation:

9x² + 6x +1 = 0.

To solve the quadratic equation, we can write it as:

9x² + 6x + 1 = 0

9x² + 3x + 3x + 1 = 0

Taking the common factor out, we get:

3x (3x + 1) +1 (3x+1) = 0

(3x+1) * (3x + 1) = 0

(3x+1)² = 0

3x + 1 = 0

3x = - 1

x = -1/ 3

Thus solved. Value of x is -1/3.
