ok... you need to find the factors of   18  called p   

$$1 \times 18, -1 \times -18, 2 \times 9, -2 \times -9, 3 \times 6, -3 \times - 6$$

and factors of -2 called q 

$$-1 \times 2, 1 \times -2 $$

then find all the combinations of p/q   

then find 

f(p/q) if there is a zero remainder p/q is a factor of f(x)
