To be honest that doesn't look like an integral that could be given to a 2U student without first prompting them to differentiate . I might be missing something but I don't see how you could do that using only 2U methods.

it's actually the second part of a question,
it originally asked us to differentiate x^2e^x
and then hence find ∫x(x+2)e^x dx , i knew the answer should be x^2e^x because that was basically given to us in the first part, but getting to it was what i was stuck with.
but thank you :)

Oh. Just expand the integrand then.

You'll get , and then the integration should be easy.
