Answer:
The correct answer is x = -7 and x = 1. To solve this equation using the completing the square method, we first need to subtract 13 from both sides of the equation. We then need to add 49/4 to both sides of the equation. This gives us (x + 7/2)^2 = 49/4. We then take the square root of both sides of the equation to get x + 7/2 = 7/2 or x = -7. We can then solve for the other value of x by subtracting 7/2 from both sides of the equation, giving us x = 1.
