How to define the coefficients of a polynomial to be real?


I have a 10th order polynomial (a0+a1 z+a2 z^2 + ... + an z^10). I
want to define all the coefficients to be real. I want to substitute z
= 1+i and extract only real part of it.

I have done this by defining

Element[a0,Reals];
Element[a1,Reals];
