Question

Solve : 9x² + 6x + 1 = 0.

Answer 1

Answer:

x = -1/3       ;    x = -1/3

Explanation:

9x² + 6x + 1 = 0

9x² + 3x + 3x + 1 = 0 (since, 3 * 3 = 9)

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

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

Therefore zeroes are =>

3x + 1 = 0   ;  3x + 1 = 0

3x = -1        ;  3x = -1

x = -1/3       ;    x = -1/3

hope this helps !

please mark this as the brainliest answer !!!!
