Problem:
Compute
$\left(
\begin{array}{ccc}
 \frac{1}{2} & -2 & -\frac{5}{2} \\
 -3 & \frac{5}{2} & -\frac{5}{2} \\
 0 & -1 & \frac{1}{2} \\
\end{array}
\right)^2$.
Answer:
$\left(
\begin{array}{ccc}
 \frac{25}{4} & -\frac{7}{2} & \frac{5}{2} \\
 -9 & \frac{59}{4} & 0 \\
 3 & -3 & \frac{11}{4} \\
\end{array}
\right)$
