2008 AIME I Problem 13

Let

p(x,y) = a_0 + a_1x + a_2y + a_3x^2 + a_4xy + a_5y^2 + a_6x^3 + a_7x^2y + a_8xy^2 + a_9y^3.

Suppose that

p(0,0) = p(1,0) = p( - 1,0) = p(0,1) = p(0, - 1) = p(1,1) = p(1, - 1) = p(2,2) = 0.

There is a point \left(\frac {a}{c},\frac {b}{c}\right) for which p\left(\frac {a}{c},\frac {b}{c}\right) = 0 for all such polynomials, where a, b, and c are positive integers, a and c are relatively prime, and c > 1. Find a + b + c.

Leading zeroes must be inputted, so if your answer is 34, then input 034
