Best ResponseYou've already chosen the best response.0You almost had it. You got the correct antiderivative, \[x^2e^{x}2xe^{x}2e^{x}\] But you didn't answer the question, it wants the integral of the original function from x=0 to a. So you must do \[\left(x^2e^{x}2xe^{x}2e^{x}\right_0^a=a^2e^{a}2ae^{a}2e^{a}+2\]
