Let G be a graph and let m _ij ( G ) , i, j ≥ 1, represents the number of edge of G , where i and j are the degrees of vertices u and v respectively. In this article, we will compute different polynomials of flower graph f ( _n×m ), namely M polynomial and Forgotten polynomial. These polynomials will help us to find many degree based topological indices, included different Zagreb indices, harmonic indices and forgotten index.
