The aim of this paper is to study properties of the third-order
delay trinomial differential equation , by transforming this equation onto the second-/third-order binomial differential
equation. Using suitable comparison theorems, we establish new results on
asymptotic behavior of solutions of the studied equations. Obtained criteria
improve and generalize earlier ones.
