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.
