Please help me to do the following first three step calculate by hand, last two step plot with MATLAB code.

Thank you.

Consider following linear system, -3 1 * x + -2 Design an observer and assign the observer poles at -12, -15. When u=0.2, find x(c) and yo) When u=0.2, find X(0)and (0) = AX + Bu + Key - y) = AX + Bu + Key - Cx - Du) Plot error of states of estimator when Xo = [221] Plot error of output of estimator when fo = [2122] .
