# two column enumeration in beamer slide

I have tried to obtain two column choices in beamer using the code below:

\documentclass[aspectratio=169]{beamer}
\usetheme[height=16mm]{Rochester}
\usepackage{textpos}
\usepackage{amsmath}
\usepackage{multicol}
%\setbeamercolor{background canvas}{bg=white!20}
%\logo{\includegraphics[height=0.8cm]{Picture2.png}\vspace{220pt}}
\begin{textblock*}{100mm}(.85\textwidth,-1cm)
\Huge\textcolor{white}{\includegraphics[height=0.8cm]{Picture2.jpg}\vspace{220pt}}
\end{textblock*}}
\setbeamercolor{background canvas}{bg=white!20}
\title{KCET CRASH COURSE}
\author{G Ekaveera}

%\usetheme{lucid}
\begin{document}
\frame {
\titlepage
}
\frame {
\frametitle{Definition }

An equation of the form $ax^2+bx+c=0$ where $a \ne 0$

and $a,b,c \in \mathbb{C}$
}
\frame{
%\framesubtitle{A factor which converts LHS in to Exact Differential }
The roots are given by $$\alpha=\frac{-b+\sqrt{b^2-4ac}}{2a}$$

and $$\beta=\frac{-b-\sqrt{b^2-4ac}}{2a}$$

Where $D=b^2-4ac$ is called Discriminant of the Quadratic
}
\frame{
\frametitle{Relation between roots and coefficients}

\framesubtitle{Sum and Product of the roots}
$$\alpha+\beta=\frac{-b}{a}$$

$$\alpha \times \beta=\frac{c}{a}$$

}

%By product rule of differentiation we get:

%$$R(x)\frac{dy}{dx}+yR'(x)=Q(x)R(x) -(3)$$

\frame {
\frametitle{Nature of the roots}
If $a,b,c \in \mathbb{R}$
\begin{enumerate}
\item If $D > 0$ roots are real and distinct
\item If $D=0$ roots are real and equal
\item if $D <0$ roots are complex conjugates
\item D is discriminant
\end{enumerate}
}
\end{document}


But I get choices in single column. How to get choices in two column?

• I'm not sure which "choices" your are talking about. Do you want the enumeration in two columns? – user36296 Mar 14 at 16:55
• Yes ofcourse thats what i asked – Ekaveera Mar 14 at 16:56
• off-topic: don't use $$....$$ for equations: Why is $…$ preferable to ? – user36296 Mar 14 at 16:57
• off-topic: \begin{frame}{my frametitle}...\end{frame} is much more readable... – koleygr Mar 14 at 16:58
• ya i used double dollar for centered alignment of equation – Ekaveera Mar 14 at 16:58

You could split the enumeration into two parts:

\documentclass[aspectratio=169]{beamer}

\usepackage{textpos}

\usetheme[height=16mm]{Rochester}
\begin{textblock*}{100mm}(.85\textwidth,-1cm)
\Huge\textcolor{white}{\includegraphics[height=0.8cm]{example-image}\vspace{220pt}}
\end{textblock*}
}
\setbeamercolor{background canvas}{bg=white!20}

\begin{document}

\begin{frame}
\frametitle{Nature of the roots}
If $a,b,c \in \mathbb{R}$
\begin{columns}
\begin{column}{.45\textwidth}
\begin{enumerate}
\item If $D > 0$ roots are real and distinct
\item If $D=0$ roots are real and equal
\end{enumerate}
\end{column}
\begin{column}{.45\textwidth}
\begin{enumerate}
\item if $D <0$ roots are complex conjugates
\item D is discriminant
\end{enumerate}
\end{column}
\end{columns}
\end{frame}

\end{document}


• Excellent. will the same applicable if i use \begin {choices}? – Ekaveera Mar 14 at 17:05
• @Ekaveera I don't know which package you use or how you define \begin{choices}, so I have no idea. – user36296 Mar 14 at 17:06
• Thanks what do you mean by enumi – Ekaveera Mar 14 at 17:16
• @Ekaveera That's the name of the counter for the numeration of the items – user36296 Mar 14 at 17:19
