    Using Generic Account's info and correcting an error....

    ........5x²-x+10

    ........----------------------------

    (x-4)\(5x³-21x²+14x-40)

    ........5x³-20x²

    ........-------------

    ............0 - x² + 14x

    .............. - x² + 4x

    ...............----------------

    ...............0 + 10x - 40

    ...................+ 10x - 40

    .......................-------------
