    I understand how to use Matlab to graph the loci, but I need help to understand how to graph the loci by hand.

    Sketch the Loci and find range of K for stability for these two problems

    K(s+1)
    ------------------
    (s-1)(s^2 + 4s + 16)

    and

    K
    -------------------
    (s-1)(s^2 + 4s + 7)
