Abstract	In this research paper, we investigate new subclasses R_∑▒‍^(μ,q,m) (λ,ϕ,γ,β,t) and UAR_∑▒‍^(λ,q,m) (ϕ,γ,β,t) of bi-univalent functions defined on the unit disk Δ in the complex plane using Opoola differential operator and quasi-subordination. Further, we find upper bounds of \|a_2 \| and \|a_3 \| for functions in these new subclasses.
