Problem:
Find the characteristic polynomial of the following matrix:
$\left(
\begin{array}{ccc}
 -\frac{101}{25} & \frac{437}{50} & \frac{293}{100} \\
 -\frac{223}{50} & \frac{123}{100} & \frac{771}{100} \\
 \frac{303}{100} & -\frac{121}{25} & -\frac{249}{25} \\
\end{array}
\right)$
Answer:
$-x^3-\frac{1277 x^2}{100}-\frac{904373 x}{10000}-\frac{233003711}{1000000}$
