The Rational Root Theorem states that if a polynomial equation is of the form $a_nx^n + a_{n-1}x^{n-1} + ... + a_1x + a_0 = 0$, then any rational root of the equation must be of the form $\pm \frac{p}{q}$, where $p$ is a factor of $a_0$ and $q$ is a factor of $a_n$.
For the equation given, $a_n = 2$, $a_{n-1} = -1$, $a_1 = 2$, and $a_0 = 5$.
Factors of $a_0 = 5$ are $\pm 1, \pm 5$
Factors of $a_n = 2$ are $\pm 1, \pm 2$
Therefore, the possible rational roots are:
$\pm 1, \pm 5, \pm \frac{1}{2}, \pm \frac{5}{2}$
