✦ Synopsis
We present a method for factoring polynomials of the shape f X y f Y , where f is a univariate polynomial over a field k. We then apply this method in the case when f is a member of the infinite family of exceptional polynomials we Ž . Ž . discovered jointly with H. Lenstra in 1995; factoring f X y f Y in this case was posed as a problem by S. Cohen shortly after the discovery of these polynomials.
