Best ResponseYou've already chosen the best response.0if I recall correctly, that means your trying to find the original function that this was derived from correct?

Best ResponseYou've already chosen the best response.0the only method I remember off hand is the seperation of variables.... have you tried that yet?

Best ResponseYou've already chosen the best response.0i think seperation variable is not correct for this equation

Best ResponseYou've already chosen the best response.0You can use the method: multiplying with an integrating factor. divide everything by x, so you'll have y'+2/x y=x. The integrating factor will then be: e^{2\int 1/x}=e^{2lnx}=e^{ln(x^2)}=x^2.

Best ResponseYou've already chosen the best response.0Multiply both sides by the integrating factor x^2, then the left side will be (y*x^2)'. The right side is x^3. Then you integrate both sides, and gets y*x^2={1/4} *x^4+C Divide both sides of the equation by x^2 and you have the answer :) If you're not familiar with the method and wants a further explanation, just tell me...

Best ResponseYou've already chosen the best response.0Yes, it is correct. y=... , youre right. I only looked too much at the latter posts instead of where your answer was, I'm sorry for that..
