Abstract :
Oscillation criterion is investigated for all solutions of the first-order linear neutral differential equations with positive and negative coefficients. Some sufficient conditionsare established so that every solution ofeq.(1.1) oscillate.Generalizing of some results in [4] and [5] are given.Examples are given toillustrated our main results
