# Sums and polynomials?

**Algebra**Level 5

Given

\[S=\sum_{x=0}^{\infty}\frac {4x \choose x}{2^{4x+1}(3x+1)},\]

\(S\) is the root of a monic third degree polynomial with integral coefficients. Find the sum of coefficients of the polynomial.

This problem would not be possible if not for the awesome problem The Hydra. A good tip would be to try out that problem first.
