In parts (a) through (f), sketch the root locus plot for the given characteristic equation for K

Question:

In parts (a) through (f), sketch the root locus plot for the given characteristic equation for K ≥ 0.
s(s + 5) + K .= 0
s(s + 7)(s + 9) + K = 0
s2 + 3s + 5 + K(s + 3) = 0
s(s + 4) + K(s + 5) = 0
s(s2 + 3s + 5) + K = 0
s{s + 3)(s + T) + K(s + 4) = 0
