this equation in not saparable so i need to find the integration coefficient? is there easier way it looks like bernuly but i am not sure because of the square root

If by "integration coefficient" you mean "integrating factor", that technique only works on first-order linear equations, which this obviously is not. Why not try the Bernoulli approach? Standard form would be So the substitution would be what?
Setting You obtain... (1) ... that is a linear first order ODE and can be 'attacked' in usual way... Kind regards

You're welcome for my contribution. Incidentally, I believe that the Bernoulli approach would use the same substitution that chisigma proposed.
