Hi, I need help with this Hassel-type model question. I'm very stuck so I need to see an expert show me how to do the question! Ty!

Consider the Hassell-type model Ront nt+1 = (1 + ant)2 where a > 0, Ro > 0. (a) Now suppose that in each time step t+t+1, a fraction E of the population size ne (measured at time t) is removed immediately before nt+1 is measured leading to the model Ro Nt+1 Ent. (1 + an) Determine conditions on E for the harvested model to have a positive steady state. Consider the Hassell-type model Ront nt+1 = (1 + ant)2 where a > 0, Ro > 0.
