thank god...u really help me very much :D :D

the problem is (x+x^4)dy+y(y^3-x^3)dx=0 well I know that this is not a separable equation, homogenous equation or an exact equation...so i try to solve it by treating it as a non exact DE by finding out the integrating factor...but the both IF come out in term of x and y which involve 2...
