    Integration by Parts Check

    Just learning these and I wanted to make sure I did this right.

    I'm finding the integral of 2x(e^x) in case it's not clear.

    Let me know. Thanks.

    Looks good. I'd suggest getting into the habit of factoring answers, but it doesn't actually matter here. Also, as this is indefinite integration, you need to remember the +C constant at the end.

    You could always differentiate your answer. If it matches the original integrand, then your answer is correct.
