Exercise3

Use the techniques we have seen in this section to find the eigenvalues of the matrix

\begin{equation*} A= \left[\begin{array}{rrrrr} -14.6 \amp 9.0 \amp -14.1 \amp 5.8 \amp 13.0 \\ 27.8 \amp -4.2 \amp 16.0 \amp 0.9 \amp -21.3 \\ -5.5 \amp 3.4 \amp 3.4 \amp 3.3 \amp 1.1 \\ -25.4 \amp 11.3 \amp -15.4 \amp 4.7 \amp 20.3 \\ -33.7 \amp 14.8 \amp -22.5 \amp 9.7 \amp 26.6 \\ \end{array}\right] \text{.} \end{equation*}
