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.
