Solve using the square root property

Question

I need help with this math problem. I know the answer is -8 and -2 I just don't know the steps to get there. If you could help me with this please.

(x+5)^2 = 0

Answer 1

Or alternatively...

 

1.  √((x+5)²) = √0

 

2. (x+5) = 0

 

3. x + 5 - 5 = 0 - 5

 

4. x = -5

 

How did you come up with -8 and -2?

Answer 2

(x + 5)² = 0 ----> (x + 5)(x + 5) = 0 ---> x + 5 = 0 ---> x = -5
