Answer:

x = -8 or 8

Step-by-step explanation:

So, we need to know when x^2  - 6x - 16 = 0.

Let's solve this! :)

We can add 16 to both sides:

x^2 - 6x = 16

Now, we can simply tell that x^2 has to be 16 more than -6x, so the answer must be smaller than -6 or greater than 6.

By making an educated guess, we get x = -8 or x = 8 :)
