This paper deals with the study of Bianchi type-I universe in the context of gravity. Einstein’s field equations in gravity have been solved in the presence of cosmological constant and quadratic equation of state (EoS) , where is a constant. Here, we have discussed two classes of gravity; that is, and . A set of models has been taken into consideration based on the plausible relation. Also, we have studied some physical and kinematical properties of the models.
