1. All real solutions of Eq. (F-20) are breakaway points on the root loci for all values
of K, since the entire real axis of the s-plane is occupied by the root loci.
2. The complex-conjugate solutions of Eq. (F-20) are breakaway points only if they
satisfy the characteristic equation or are points on the root loci.
3. Since the condition of the root loci is
