Can you help me solve this integral?
integral of x^2e^-x^3
I have tried Integration by parts and substitution but NOT working.
Any ideas?

set u=-x^3
so then du = -3x^2dx
so the integral gets simplified to:
-(1/3)e^u
The integration of that is -(1/3)e^u
replug the u back in
-(1/3)e^(-x^3)

I solved it using substitution. The answer is -1/3e^X^3

try substitution again and you will find your answer
