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 :)

how does one integrate ∫x(x+2)e^x dx answer ends up x^2e^x + c thanks in advance :)

Legend! Thank you so much

In a pyramid in Egypt, the triangular sides are formed by rows of stone blocks. Each row has one less block than the row beneath it. If the bottom row of one side has 300 blocks in it, how many blocks were needed to form the side? If every corner block is shared by two sides, how many blocks...
