Simple integral

    integral (x^2 - 2x) e^-x dx

    Im just wondering if theres a fast way to calculate this integral or is the only way to do it by parts twice. The prof didnt show any work in the solution and went right to the solution. Am I missing something obvious?

    I think your plan of using integration by parts is the way to go.
