Question

Ignore my work,I was just seeing if I know how to work the problem.​

Answer 1

The values of x are 4, -4, and -2.

We can solve this by simply factorising the (x² - 16) bracket into a difference of two squares, to give us (x + 4)(x - 4), and then setting each bracket equal to 0.

When x + 2 = 0, x = -2

When x + 4 = 0, x = -4

When x - 4 = 0, x = 4

I hope this helps!
