I am using Crank–Nicolson to solve a logistic function, modeling population growth.

To get the next time step, I have to solve a quadratic equation.

The problem is that i get two solutions for y(i+1). Does it mean that I am doing it wrong?

If not, can I just pick the solution that is closest to y(i)?
