What are the solutions of the quadratic equation (x + 3) 2 = 49?

Ox=-2 and x = - 16

x = 2 and x = - 10

O x = 4 and x = - 10

O x = 40 and x = - 58

4 and - 10

Step-by-step explanation:

Take the square root of both sides of (x + 3) ^2 = 49, obtaining:

x + 3 = ± 7

Then either x + 3 = 7 or x + 3 = - 7.

In the first case, x = 4; in the second case, x = - 10.
