You can't have roots if you don't have an equation. A third degree polynomial has three zeros. The rational roots theorem applied to the given polynomial says that there are only two possible rational zeros, namely 1 and -1. Using synthetic division, we find that neither 1 nor -1 is indeed a zero, hence there are zero rational zeros for the given polynomial.
