Best ResponseYou've already chosen the best response.1its pretty long. but my answer is ln x [ x  (x^2/2) ]  x  (x^2/4) + C

Best ResponseYou've already chosen the best response.0yeah, u sub wouldn't work since u = ln(x), du = dx/x , x*du = dx.

Best ResponseYou've already chosen the best response.0oh I think except for a minus sign... ln x [ x  (x^2/2) ]  x + (x^2/4) + C
