Captions on the right to math

Question

I'm trying to write something like this:

\begin{itemize}
\item \(x^2+y^2-1=0; \quad\quad\quad\) (ellipse)
\item \(x^2-y^2-1=0; \quad\quad\quad\) (hyperbola)
\item \(x^2-y=0; \quad\quad\quad\) (parabola)
\end{itemize}

I'm struggling to find out how to make it right without using all those \quad and aligning the captions. Thanks in andvance

Thank you! Well, it solves the problem but not the way I was thinking about. I wanted the captions to be right-aligned. It isn't a serious problem though - but if it is possible, I'd love to hear how — johncrimes, Mar 27 '21 at 21:48

One option that does not seem to get mentioned in Custom alignment of text in itemized environment is to use eqparbox. It allows you to create boxes of equal width. In more detail all boxes with the same id have the same width. And you can blend this into a macro that allows to further unnecessary repetition. If you use it in another enumerate environment, use a new id.

\documentclass{article}
\usepackage{eqparbox}
\newcommand\MyItem[2][someid]{\item \eqmakebox[#1][l]{$#2;$}\qquad}
\begin{document}
\begin{itemize}
\MyItem{x^2+y^2-1=0} (ellipse)
\MyItem{x^2-y^2-1=0} (hyperbola)
\MyItem{x^2-y=0} (parabola)
\end{itemize}
\end{document}
