What are the solutions to the quadratic equation x2 - 16 = 0?

O x = 2 and x = - 2

x = 4 and x = - 4

x = 8 and x = - 8

x = 16 and x = - 16

Answer: x=8 and x=-8

Step-by-step explanation:

To find the solutions of the quadratic equation, you want to factor it and set it equal to 0.

x²-16=0

(x+8) (x-8) = 0

x+8=0

x=-8

x-8=0

x=8

Now that we have factored and set the factors equal to 0, we found that the solutions are x=-8 and x=8.
