make vertical fill inside multicols environment

Question

I want to have the right column not to be stretched by using \vfill. The source code I used is this.

\begin{multicols}{2}
    \noindent
    \begin{enumerate}
        \item $ x^{2} - 7x + 10 = 0 $
        \item $ 2x^{2} - 5x - 9 = 0 $
        \item $ 7x^{2} + x - 1 = 0 $
        \item $ x^{2} + 4x + 4 = 0 $
        \item $ x^{2} + x + 1 = 0 $
    \end{enumerate}
    \vfill
\end{multicols}

The code above will produce something like this

We can see that the right column is stretched. I don't want it to be like this. So I add \vfill below the enumerate environment, but this doesn't fix anything.

I also try using enumerate*, but it seems that it doesn't automatically break after point c).

Thanks.

Answer 1

Multicols has a command for that (see page 4). \raggedcolumns can be used locally (inside the environment) or globally (in the preamble).

You can also use \vspace*{\fill}.

\documentclass[letterpaper]{article}
\usepackage{multicol,amsmath}
\usepackage{enumitem}
\begin{document}
\begin{multicols}{2}
    \noindent
    \begin{enumerate}
        \item $ x^{2} - 7x + 10 = 0 $
        \item $ 2x^{2} - 5x - 9 = 0 $
        \item $ 7x^{2} + x - 1 = 0 $
        \item $ x^{2} + 4x + 4 = 0 $
        \item $ x^{2} + x + 1 = 0 $
    \end{enumerate}
    \raggedcolumns
\end{multicols}
\end{document}

Answer 2

Here is MWE:

\documentclass[letterpaper]{article}
\usepackage{multicol,amsmath}
\usepackage{enumitem}
\begin{document}
\begin{multicols}{2}
    \noindent
    \begin{enumerate}
        \item $ x^{2} - 7x + 10 = 0 $
        \item $ 2x^{2} - 5x - 9 = 0 $
        \item $ 7x^{2} + x - 1 = 0 $
        \item $ x^{2} + 4x + 4 = 0 $
        \item $ x^{2} + x + 1 = 0 $
        \item[]
    \end{enumerate}
\end{multicols}
\end{document}

Note that the other answer below makes more sense since it will auto adjust the columns. Essentially, what you are trying to do is fill the vertical gap. You can use the suggested \vspace*{\fill} or \vfill\null or \vfill\mbox{} after your enumerate.

\begin{multicols}{2}
    \noindent
    \begin{enumerate}
        \item $ x^{2} - 7x + 10 = 0 $
        \item $ 2x^{2} - 5x - 9 = 0 $
        \item $ 7x^{2} + x - 1 = 0 $
        \item $ x^{2} + 4x + 4 = 0 $
        \item $ x^{2} + x + 1 = 0 $
    \end{enumerate}
    \vspace*{\fill}% or \vfill\null or \vfill\mbox{}
\end{multicols}
