Question

Which are solutions of the equation x2 - 16 = 0? Check all that apply.

Answer 1

Answer:

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.
