Problem $10$Develop a simple second$-$order approximationG$($s$)=$ As$2+2$ns $+2$n$,$for the complicated systemT$($s$)=1$s$4+10$s$3+33$s$2+46$s $+30.$Explain why A cannot be equal to one. Use MATLAB to plot the step responses for G$($s$)$ and T$($s$)$ andcompare. HINT: The MATLAB command r$=$roots$($p$)$ will factor T$($s$)$ for you.
