Juliet Haney · Answer 1

yes, x^ 2 - 16 is equal two (x+4) (x-4), which is a differnce between two squares ot the formula, a^2-b = (a+b) (a-b)

Sawyer Melton · Answer 2

x1 = - 4

x2 = 4

Step-by-step explanation:

Set the equation equal to zero

x2 - 16 = 0

then

(x + 4) (x - 4) = 0

(x+4) = 0 which is equal to - 4

and

(x-4) = 0 equals 4
