Conflict between polynom packages and slovak babel

Question

My problem is the conflict between polynomial long division provided by the polynom package and Slovak babel.

I want to get the polynomial long division, I use the package polynom and the following command:

\usepackage{polynom}

\polyset{style=C,div=:,vars=x}
\polylongdiv{x^3-2x^2+3x-1}{x-1}

Without using slovak babel, the output is correct:

But when I add \usepackage[slovak]{babel}, I get

As you can see the output with slovak babel active is wrong.

Any idea what might be causing this behaviour is much appreciated. Thank you!

Answer 1

The problem is similar for the Czech language, but requires a slightly different solution.

\documentclass{article}
\usepackage[main=slovak]{babel}
\usepackage{amsmath}
\usepackage{polynom}
\usepackage{xpatch}

\xpatchcmd{\polylongdiv}
  {\begingroup}
  {\begingroup\catcode`^=7 \shorthandoff{-}}
  {}{}

\polyset{style=C,div=:,vars=x}

\begin{document}

\polylongdiv{x^3-2x^2+3x-1}{x-1}

\end{document}
