x=-4

x=4

Step-by-step explanation:

We can factor x^2 - 16 = 0 by recognizing that it is a difference of squares. That means we can factor the equation to (x-4) (x+4) = 0. By using the Zero Product Property we know that either (x-4) or (x+4) is equal to 0. That means that x either equals - 4 or 4.
