just trying to figure out this integral int(x^2 (1+x^3)^4 dx)

when i integrate by substitution i get anti deriv.... 1/15 (1+x^3)^5

which is not the same (but close when u plug in values of x) to

1/15*x^15 +1/3*x^12 + 2/3*x^9 + 2/3*x^6 + 1/3*x^3

am i going about this wrong?....i'm letting u = 1 + x^3...what
