  We apply the technique of standard supersymmetric factorization for any q
factor ordering in the Wheeler-DeWitt (WDW) equation for barotropic
Friedmann-Robertson-Walker (FRW) minisuperspace model, including the
cosmological term. The resulting wave functions of the universe are exhibited
as one-parameter families, which for particular values of the $\gamma$
parameter of the barotropic model are exactly found.
