    I can only find one, I just found y = (1-Ae^(-2x))/2 where A = e^2c

    are you given multiple initial conditions?

    \[dy/(1-2y)=dx\] \[\sqrt{1-2y}=Ce ^{x}\] \[1-2y = \pm Ce ^{x}\]

    I mean remember absolute value with\[\int\frac{du}u=\ln|u|+C\] :P

    that comes out nicely from the square root anyway
