Unity feed-back control system with the following feedforward transfer function : Root loci

Consider a unity feed-back control system with the following feedforward transfer function:

G(s) = K(s^2+25)s/s^4+404s^2+1600

Plot the root locus (or root loci) for the system with MATLAB. Show that the system is stable for all values of K>0.
