NEed help with these two equations. Everything is written on the picture

Find the characteristic equation Find the roots of the characteristic equation, and determine whether or not the system is stable. For stable systems, determine: i. The system's time constant and settling time ii. All damped natural frequencies, and their associated damping ratios Write the general form of the homogeneous solution 2am + 18550) + 62W) + 118%) + \"05\"\") : 0 350:) + 2353) , 6w) + 8d:(t) + 80w(t) = 0
