In a recent issue of this Bulletin a problem equivalent to the following is proposed by Moser and Pounder [1]:If ax2+bx+c is a polynomial with real coefficients and real roots then a+b+c ≤9/4 max (a, b, c).The object of this note is to prove the following theorems which generalise this result.Theorem 1. Let αn be the smallest constant such that n for all polynomials 1
