             n^2 - 8n + 12

          __________________   , Remember that n^3 - 12n^2 + 36n≠0

           n^3 - 12n^2 + 36n



            Factor both numerator and denominator



            (n - 6)(n - 2)

           _______________ , n ≠ 6, so 6 is the excluded value

            (n - 6)(n - 6)



           Divide the common factor/s

           cross%28n+-+6%29%28n+-+2%29

           ______________

           cross%28n+-+6%29%28n+-+6%29







           (n - 2)

           _______    -------->> answer

           (n - 6)
