-x3+6x2-11x+6=-x3+x2+5x2-5x-6x+6=
                       =-x2(x-1)+5x(x-1)-6(x-1)=
                       =-(x-1)(x2-5x+6)=
                       =-(x-1)(x-2)(x-3)

Note that in going from: 
-x2(x-1)+5x(x-1)-6(x-1)=
=-(x-1)(x2-5x+6)
A negative 1 was also factored out of: -x2 + 5x - 6 to get -(x2-5x+6)
