The problem is in the picture

x = 3 or 7

Step-by-step explanation:

Solve by completing the square:

First, move the constants to one side:

Then, add to both sides to make the right a perfect square trinomial, which is easy to factor:

Simplify and Factor:

Finally, square root both sides using the even roots property:

x - 5 = ± 2

x = 5 ± 2

x = 3   or   x = 7
