In this paper a general fixed point theorem of generalized Greguš type in symmetric spac-es for hybrid pair satisfying a new type of implicit relation using generalized altering dis-tance and we obtain simultaneous results for contractive and extensive mappings. As ap-plication, new results for hybrid pairs satisfying contractive and expansive conditions of integral type are obtained.
