There are 2 ways to solve this Differential Equation:
1) Since it is linear in y use F1 : Linear in y
enter P=-x^2
and Q=2x^3
press Enter . Using an Integration factor will yield the answer.
2) Rewriting it as y’=2x^2+x^2*y=x^2*(2+y) shows that the method of separating the variables will work as well, That is under F1: Separation of Variable
Two different methods will yield the same correct solution.
