Oscillatory and asymptotic behaviour of the solutions of a class of nonlinear rst order neutral delay dierential equa- tions with positive and negative coecients of the form E1 ...[wzór] are studied under various ranges of p(t). Sufficient conditions are obtained for the existence of positive bounded solution of (E2).
