Answer:
-6,2
Explanation:
f(x) = (x + 2)^2 - 16
Set this equal to zero to find the solutions
0 = (x + 2)^2 - 16
Add 16 to each side
16 = (x + 2)^2
Take the square root of each side
±sqrt(16) = sqrt( (x + 2)^2)
±4 = x+2
Subtract 2 from each side
±4 -2 = x+2-2
±4 -2 = x
4-2 = x
-4-2 =x
2, -6
In order from least to greatest
-6,2
