Problem:
Find the characteristic polynomial of the following matrix:
$\left(
\begin{array}{ccc}
 -\frac{95}{16} & \frac{29}{8} & -\frac{73}{16} \\
 \frac{99}{16} & \frac{3}{8} & \frac{7}{8} \\
 \frac{9}{2} & -\frac{103}{16} & \frac{49}{8} \\
\end{array}
\right)$
Answer:
$-x^3+\frac{9 x^2}{16}+\frac{521 x}{16}+\frac{78815}{4096}$
