Yet a number of trends seem to portend deep change in how the textbook is conceived and used. Few instructors are satisfied with the textbook: “It covers too many topics, it does them in the wrong orde...

We consider trinomials of the form zn+azm+b, where 0<m<n are relatively prime integers and a b nonzero complex numbers. Typically (but not exclusively), will be an integer with |a|≥2, while b=±1. Our main results cover irreducibility, Mahler measure house such trinomials.
