Question: how to Rearrange an Equation to a transfer function form in Maple?

I tried to simplify this equation:

where Ts,Cf,Rf,Lg & L are Variables to equivelent equation in the form of:

                                                         (.....)Z3+(....)Z2+(.....)Z+(.........)      /   (.....)Z3+(....)Z2+(.....)Z+(.........)
