    The parts of the diagram are very clearly labelled. Good :)
    You have also shown very clearly how to evaluate the expression by subtracting the areas of parts of the rectangle.

    Please expand the same expression using the FOIL method (show the working with the arrows would be good). Then insert the image in this SAME post.
