## Homework Statement

Determine the number of solutions in nonegative intergers to the equation:

a + 2b + 4c = 10[tex]^{30}[/tex]

## Homework Equations

The generating function I've found is f(x) = 1/[(1-x[tex]^{4}[/tex])(1-x[tex]^{2}[/tex])(1-x)]

## The Attempt at a Solution

I'm pretty sure I need to get from here to an explicit formula, but I'm not sure how to start. Any hints to get me started on this one?
