Letpandqbe a monic hyperbolic polynomials such thatqseparatespand letHbe the Bézoutian (form) ofpandq. ThenHis nonnegative definite and symmetrizes the Sylvester matrix associated withp. Whenthis fact is observed by E. Jannelli. We give a simple proof of this fact and at the same time prove that the family of Bézoutian of Nuij approximation ofpandgives quasi-symmetrizers introduced by S. Spagnolo. A relation connectingHwith the symmetrizer which was used by J. Leray for strictly hyperbolic polynomials is also given.
