OK, I think I got it to work. I did a bunch of things (mostly uninformed), and some combination of them seems to have worked, but I'm guessing these were the three key steps: 1. I installed the polynom package and put it in my LaTeX directory: C:\Program Files\MiKTeX 2.7\tex\latex. I probably could have put it somewhere else in my path; I'm not sure. 2. In LyX, I did Tools --> Reconfigure 3. In my document, I did Document --> Settings --> LaTeX preamble, and added the following, which I more or less copied from some LyX help files: % ------------------------------------ % used to check for needed LaTeX packages \usepackage{ifthen}
% check for package polynom \newboolean{polynom} \IfFileExists{polynom.sty} {\usepackage{polynom} \setboolean{polynom}{true}} {\setboolean{polynom}{false}} Then, in my document, I can click Insert --> TeX Code (or Control-L, or click on the TeX button), and enter the TeX code for polynomial division, e.g. \polylongdiv{x^3-7x+6}{x-1}. Then when I compile the document (e.g. click the PDF button), the division is beautifully formatted.
