    In the first diagram, you have labelled the parts and shaded them correctly.

    However, you have not describe how to evaluate the expression using the area of rectangles in the diagram.
    Please add the "area" for each part of the rectangular in your diagram. Then followed by subtraction, so as to illustrate how we could show the expansion method in a more concrete manner.

    In the 2nd diagram, the arrows seem to be running correctly. However, because it is very small and was written in pencil, I'm unable to read it. Please use pen (ink) the next time.

    Did you also notice that teh photos are showing a mirror image? Do you know how to flip the diagram?
