Mathematica: Delete constant term of f(z,w)

  1. Oct 19, 2012 #1
    Hi,

    I have a messy expression as a polynomial in z and w:

    a+bz+czw+dz^2w+...+kz^n w^m

    How can I delete the constant "a" term?

    Here's the function. The constant terms are dispersed throughout the expression. I know I can extract the coefficient list first in w then in z to actually get the constant expression but I don't know how to remove it from the expression:

    Edit: Ok, that was dumb. Just use Coefficient to get at it then just subtract it out. Sorry. Can't delete it. Nevermind.
