\documentclass[]{article}
\usepackage{mathtools}
\usepackage{pstricks-add}
\usepackage{varwidth}

\begin{document}

\begin{pspicture}[showgrid](10,10)
\rput[lb](1,1){\psframebox*[fillcolor=red!40]{\parbox{0.5\linewidth}{%		
   \begin{align*}
     I & = \int_1^4 (u-1)\sqrt{u} \, du  \\
       & = \int_1^4 \left(u^{\frac{3}{2}}-u^{\frac{1}{2}}\right) \, du  \\
       & = \left[\frac{2}{5} u^{\frac{5}{2}} - 
\frac{2}{3}u^{\frac{3}{2}}\right]_1^4
   \end{align*}%
}}}
