Answer:

-5 and 9

Explanation:

I honestly could be wrong, here's how I solved it:

2x^2-8x-90

First, I factored the equation:

2(x+5)(x-9)

Then I set the x+5 and x-9 = 0

So something like this (x-5=0 which is x=5) and (x-9=0 which is 9)

Therefore, the answers are -5 and 9.

Let me know if this helps!
