A polynomial

*f*(*x*) satisfies the equation*f*(*x*)+(*x*+1)3=2*f*(*x*+1). Find*f*(10). - January 27th 2013, 12:10 PMemakarovRe: need help solving this function....
Write as (you may also add or higher degrees), write the equation in terms of , ..., and equate the coefficients of the corresponding monomials. You'll get a system of four linear equations in , ..., .
