Answer:
If you meant the equation was xe^3x
then the first derivative would be 3xe^3x+e^3x using the product rule
Then to find the second derivative you'll have to use both the product rule and sum rule inorder to get the answer.
The 2nd derivative would therefore be 9xe^3x+6e^3x or in factored form
3e^3x(3x+2)
