questions about the symbolic differential equation

consider the differential equation:

dsolve('Dx = x^2 -x')

ans =

-1/(exp(C3 + t) - 1)

I think it neglects another solution that is 1/( 1 + exp(t +c)), which
requires the value of x lies within [0,1]. Is there something wrong
with the algorithm?
