Hi,

the function Coefficient will do what you want.

Coefficient[polx,x] or Coefficient[polx,x,1]

gives the terms linear in x

Coefficient[poly,x^2] or Coefficient[polx,x,2]

gives the quadratic term

Coefficient[poly,x,{0,1,2}] or Coefficient[poly,x,Range[0,2]]

gives the zero 1 and 2. order term.
