Does anyone know how you write these brackets under certain parts of an equation?

Hi,

welcome to the board!

Just an advice: if you would post also the code of the formula, there would be agood chance that somebody would return the extended code including the underbrackets, if he doesn't have to typeset the whole formula himself.

Thanks for the welcome
Sorry, this is just a print-screen from a document online, I don't know what the code for it is. I don't need to know how typeset the whole thing, just how to get the 'underbrackets' to work

[Stefan Kottwitz]

The mathtools package provides an \underbracket command:

Code: Select all

\documentclass{article}
\usepackage{mathtools}
\begin{document}
\[
  B(x)\underbracket[0.5pt]{A(z)}C(w)
\]
\end{document}

The sytnax is \underbracket[rule thickness][bracket height]{argument}, i.e. the first two arguments are optional, for fine-tuning.

Thanks, that will work
