How can I convert a list of sets into a list of equations

add tag

2 years ago Laurenso

I have a list sets {{1,2,-3},{1,3,-4},{2,-3,-2}} How can I convert that list into a list of equations {{x^2 + 2x - 3 = 0}, {x^2 + 3 x - 4=0},{2x^2-3x-2=0}}?

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\begin{document}
	I have a list
	\[  {\{1,2,-3\},\{1,3,-4\},\{2,-3,-2\}}\]
How can I convert to list of equation
\[ {{x^2 + 2x - 3 = 0},{x^2 + 3 x - 4=0},{2x^2-3x-2=0}} \]
\end{document}

You could use a combination of the polynomial and pgffor packages:

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{pgffor}

\usepackage{polynomial}

\begin{document}

  \foreach \set in {{1,2,-3},{1,3,-4},{2,-3,-2}}{
    \[\polynomial[reciprocal]{\set}=0\]
  }

\end{document}
