    I need to find out the area under a curve between -5 and 5.
    The curve is x2-2x-24.
    Any pointers would be appreciated.

    Did it ask for an exact answer, or an estimate?

    Intergrate x^2-2x-24

    Substitute 5 into the integral

    Then substitute -5 into the integral

    Then subract the answer u get for substituting -5 into the integral from the answer u get from substituting 5 into the integral.

    I think this is correct, but it would help if I had a drawing(which I can't be bothered to draw)

    Be careful about positive/negative areas - you'll have to integrate it between -5 and -4 and -4 and 5, then add them together
