Zagreb indices (thought this paper we denote ZbI) a well-known concept introduced in 1972 by I.Gutman and N.Trinajstic denoted as()mathematically to study chemical compounds at molecular level. The first two hyper-ZbI of G denoted () and () are well established. In this paper we determine the first ZbI and second ZbI and their polynomial for the Tadpole graph
