To solve this equation, you first take the square root of both sides.
This will give you two options, because the square root of 64 could be 8 or -8.
Your equations are:
x + 3 = 8 or x + 3 = -8
Solving these equations give the solutions: x = 5 or x = -11
Option A is correct.
You can verify that it is correct by inputting the solutions and evaluating the expression.
I hope this helps, good luck!
