I want to use the polynom package for synthetic division. However, while it works well for integer roots it does not take non-integer inputs. For example this works well:

\documentclass[12pt,letterpaper,oneside]{article}
\usepackage{polynom}

\begin{document}
    \polyhornerscheme[x=4]{2x^5-3x^4-23x^3-3x^2+51x+36}
\end{document}

But I don't know how to use a non-integer such as \sqrt{3} as a root:

\polyhornerscheme[x=\sqrt{3}]{2x^5-3x^4-23x^3-3x^2+51x+36}

Are there any workarounds to this problem, or am I just better off writting out the division manually in a table.

My apologies if this is a silly question, I'm new to both LaTeX and the polynom package.

  • Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – Adam Liter Apr 20 '15 at 19:30
  • Go to http://texdoc.net/texmf-dist/doc/latex/polynom/polynom.pdf and in the documentation pg 3 it is clearly stated that it only works for integers. – R. Schumacher Apr 20 '15 at 19:46

    OK, I had just hopped that there might be some other workaround or similar package. How can I mark this question as resolved? – P-51D-25 Apr 20 '15 at 19:56
  • One of the entries in the line of small, grey words to the bottom left of your post should be 'close'. I believe that'll do it. – LSpice Apr 23 '15 at 00:49

    @LSpice There is still some chance. For example, fixing an algebraic number ζ, one can calculate its minimal polynomial by hand. Then use \polylongdiv with customized layout. – Symbol 1 Apr 24 '15 at 16:00
  • @Symbol1, is your reply directed to me or to the poster? I was just trying to advise "How can I mark this question as resolved?" – LSpice Apr 24 '15 at 16:24
  • @LSpice mainly to OP. But since my comment follows yours, I would like to ask you if it is a chance. Oh, by the way, OP would see delete instead of close. – Symbol 1 Apr 24 '15 at 16:32
  • @Symbol1, for my questions, I see both 'close' and 'delete'. Your suggestion is a neat idea, but, while the remainder returned by \polylongdiv in your suggestion will have the same value at the chosen number as the original polynomial, that still leaves the problem of finding what that value is. I don't know if that's the OP's goal, so this may or may not answer the original question. – LSpice Apr 24 '15 at 18:43
