we study the oscillatory behaviour of neutral differential equation. we obtain for the new oscillation of neutral differential equations with positive and negative coefficients. In fact ,every solution of the neutral differential equation is oscillates, while the equation has an eventually positive solution. otherwise, the equation is non oscillates, while the equation has an eventually negative solution.
