This study investigates the Hiemenz flow of hybrid nanofluid over a shrinking sheet. The similarity equations are obtained using similarity variables and then solved using the bvp4c solver. The outcomes showed that dual solutions occur for the shrinking case, in the range of 1.24657 < lambda <= -1.1 with lambda(c) = -1.24657 is the point of bifurcation between the solutions. Meanwhile, the solution is unique for lambda > -1.1. Besides, the heat transfer rate is intensified with the rise of hybrid nanoparticles. Moreover, as hybrid nanoparticles increases, the friction on the surface is increased for lambda < 1, while it is decreased for lambda > 1, and no friction occurs when lambda = 1. Finally, these solutions are tested using the stability analysis where the outcomes found that the first solution is stable and acceptable.
