Answer:

D

Explanation:

assuming you are asking for the solutions to 16*
x^(2) + 9 = 25

The goal here is to isolate X

1. subtract 9 from both sides

16*
x^(2) = 16

2. divide both sides by 16


x^(2) = 1

3. take the square root of both sides


\sqrt{x^(2) } =
√(1)

since the square root can be negative or positive

the answer is D X=1 or X=-1
