Extracting the co-efficients of the polynomial

Halo everybody In MATLAB I developed a polynomial equation of the form

a0*x^n+a1*x^(n-1)+a2*x^(n-2)+....+an=f(x) where x is a symbolic variable and a0,a1,a2,....,an are known constants.

Now I want to find the roots of this equation. Is it possible to extract the coefficients of this equation and store in a row vector so that the root command can be used to get the roots of this eqn. Can any one help in this?
