Consider the Laplace transform of state transition matrix; [ phi(s)=left[begin{array}{cc} frac{s+6}{s^{2}+6 s+5} & frac{1}{s^{2}+6 s+5} frac{-5}{s^{2}+6

Question:

Consider the Laplace transform of state transition matrix;

\[
\phi(s)=\left[\begin{array}{cc}
\frac{s+6}{s^{2}+6 s+5} & \frac{1}{s^{2}+6 s+5} \\
\frac{-5}{s^{2}+6 s+5} & \frac{s}{s^{2}+6 s+5}
\end{array}ight]
\]

The eigen values of the system are
(a) 0 and -6
(b) 1 and -5
(c) 0 and +6
(d) -1 and -5
