    How do I expand three brackets? e.g.

    (x+5)(x+7)(x-5)

    Any help would be great.

    Thanks

    Thanks a lot for the quick reply.

    I suppose the answer was obvious, I had guessed that was it, but I'm just getting back into maths study after a long break so I'm taking nothing for granted!
