# Polylongdiv: Show x^n if the coefficient = 0

I'm trying to figure out how to display x^n with 0 as coefficient in the polynom divison. I'm using the polynom package for this but the following example doesn't show x^3 and x.

Minimal example

\documentclass{article}
\usepackage{polynom}
\begin{document}
\begin{center}
\polyset{style=C,div=:,vars=x}
\polylongdiv{x^4 + 0 x^3 - 45 x^2 + 0x + 324}{x - 6}
\end{center}
\end{document}

I didn't find anything in the package's manual. So is there a solution for my problem?

• Welcome to TeX.SX! This will not be that easy as we would have to redefine the package polynom. Clearly, it decides for you not to display the zero terms and I guess, it should be possible to avoid this decision. But if you just need to type such an expression (with zeros) for one time, you should have a look here: tex.stackexchange.com/a/155609 – LaRiFaRi Jun 30 '14 at 7:41
• Thx. This solved my problem :) – Philipp Jun 30 '14 at 9:39
• Good to hear. Maybe, you just post your new formula as an answer here. And if no other solutions come up the next time, you can accept it as answer. – LaRiFaRi Jun 30 '14 at 10:38
