Answer:

Explanation:


f(x) = (x+2)^(2) - 16

First, let's expand the equation out:


f(x) = x^(2) + 4x + 4 - 16


f(x) = x^(2) + 4x - 12

Next, we can factor the quadratic equation:


f(x) = (x+6)(x-2)

Finally, to find the solutions, so the equation equal to
0:


0 = (x+6)(x-2)

From these, we know that the solutions are
x = -6, 2
