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 :)
