IVP and complex solutions

f(x,y)=-(-3*y+2*y^2)
p5sol2=desolve(diff(y,x)==f(x,y),y,ics=[0,0.5])

Returns the following:

-1/3*log(2*y(x) - 3) + 1/3*log(y(x)) == x - 26714619/25510582*I - 27229598/58926009

I get the following result from Mathematica:

y[x] -> (1.5 E^(3 x))/(2. + E^(3 x))

Why is sage returning a complex solution? I am assuming it has to do with the logs and absolute values when integrating. Any help will be appreciated. Thanks!!!
