Answer:

4±√5

EXPLAINED ANSWER:

Since the variable is a binomial and it is squared, we apply square root on both side, and apply the ± sign on the right side (since the solution of a square root can be both positive and negative), and later pass the 4 positive to the other side.

√25 can be (5)(5) or (-5)(-5)
