Abstract
In this paper, we have studied Friedmann-Robertson-Walker (FRW) cosmological model with quadratic equation of state and cosmological constant in the presence of perfect fluid source in f (R, T) gravity. To obtain an exact solution of the field equations of the theory, we have used quadratic equation of state and time dependent deceleration parameter q (t). The physical and geometrical behavior of the model is also discussed.
