Routh array :
$\left.\begin{array}{ cccccc} s^5 \\ s^4 \\ s^3 \\ s^2 \\ s \\ s^0 \end{array}\right\vert{}\ \ \begin{array}{ cccccc} 1 & 24 & 23 \\ 8 & 28 & 6 \\ 20.5 & 22.5 & \ \\ 19.317 & 6 & \ \\ 16.1325 & \ & \ \\ 6 & \ & \ \end{array}\ $
∴ there is no sign change in the 1st column of array
∴ Given polynomial is Hurwitz
