In this paper we prove that a higher-order differential equation with one middle term has every bounded solution oscillatory. Moreover, the behavior of unbounded solutions is given. Two other results dealing with positive solutions are also given.
Key words and phrases.: Higher-order equation; oscillatory, bounded, or positive solutions
