Taylor Question

I have a function, f(x), that when Taylor expanded around x=1 in maxima
gives:


                           2
         M_tot N   (M_tot N  + 2 M_tot N) (x - 1)
(%o7)/T/ ------- + ------------------------------
            2                    12
                                                2                     2
                                        (M_tot N  + 2 M_tot N) (x - 1)
                                      - -------------------------------
+ . . .
                                                      24

Is there a flag that will simplify the coefficients of (x-1) separately.
What I want is:

                                                                M_tot N
                                                                ( N+2)
                                                                --------------
                                                                   12 or
                                                                24
                                                                
for the coefficients of the x-1 and (x-1)^2 terms.  

I know how to do this manually using part() and factor(), but I'd like
to keep the Taylor form intact.
