15 POINTS! PLEASE HELP!

Given the polynomial function below, find F(-9).

F(x) = -x2 - 10x - 2

Answer 1

So this would be F(-9)=-(-9)(2)-10(-9)-2 --------
9(2)-10(-9)-2 ----------- 18+90-2 ----------- 108-2+ 106.
So the answer to this equation is 106.

Answer 2

plug in -9 where there is a x
-(-9)^2 -10 (-9) -2
X=7
