#### Explanation:

If

Given this all what we need to do here is identify the factors of

We have

so p⇒ ±1,±2 and q⇒±1,±2

and the ratio:

This are the potential roots, but remember they are not guaranteed... In this case you can try (x-1), use long division and see if you can divide without a remainder...

You were not asked to do that but you can divide
