Consider the cubic equation $245x^3 - 287x^2 + 99x - 9 = 0$ with roots $\alpha , \beta , \gamma$. If

$\displaystyle\sum_{r=0}^{\infty} \left ( \alpha^{r} + \beta^{r} + \gamma^{r} \right )$

is of the form $\frac {m}{n}$, where $m$ and $n$ are coprime positive integers, what is value of $\frac {m}{n+1}$?
