Let U = {z is an element of C : \z\ < 1} and let a1, a2, a3 is not equal to a2 be the given complex numbers. By M(01,02) we denote a family of all pairs of regular functions in U such that [...] denote the subclasses of M. of function which are univalent starlike or convex, respectively. In the paper the investigate the extrema of some functional defined on these families. In particular it is proved that [..].
