Try the same trick as on the other post: and integrate.
how ? we dont have a single dy /dx member here we have many differentiated members on both side
You have . On the RHS make the substitution so that so that your DE becomes . Now integrating both sides gives , where , where . You can integrate both sides with respect to now to find . You will need to use partial fractions.
From my previous post: On both sides, you see, the derivative of the denominator appears in the numerator. Whenever that happens, you can do a u substitution, and you'll get du/u, which integrates to ln|u|. See how that works?
