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}
```
