please help me with this assignment

Q1) Write MATLAB program to plot the root locus for the systems: GH K (s +3) $(s + 1)(s* + 4s +16) 1. K GH 2. K K s(s+0.5)(8 +0.68 +10) GH K s(s +0.5)(8 +0.65 +10) 3.K Your solution should include the code and the plot of the root locus Q2) MATLAB program produces step-response for the system: U. +3+65 Your program also should include codes to find the rise time, peak time, maximum overshoot, and settling time of the system above. - 1
