Solve. x² + 6x + 9 = 12 x = −9 ± 43√ x = −3 ± 23√ x = 3 ± 23√ x = 6 ± 43√

Step-by-step explanation:

x² + 6x + 9 = 12 → x² + 6x - 3

Since this Quadratic Expression is unfactorable, apply the Quadratic Formula:

√48 = √[3 × 16] = 4√3

½[4√3] = 2√3

Then attach half of -6 to it as well [-3]:

-3 ± 2√3
