Get you started you have to start by guessing
X=3 works
Then do long division
Answer will be x^2+12x+36
Factor
(X+6)(x+6)
3and -6 are your critical values
Now you have to test the different regions
how do I test the different regions??
Just pick a number in the region
Plug back into the function
Neg ans means less than 0
Pos ans means greater than 0
