I'm not sure I follow you there...
That's because I didn't state my hypotheses clearly

It's clearly true if the reciprocal polynomial F(z) is irreducible in Q[x] and has degree greater than 1. In this case, the zeroes occur in reciprocal pairs, so the constant term is 1. The lead coefficient is therefore also 1.
