    The diagram has all the parts well labelled.
    However, it's a bit difficult to read. Next time, use pen, please.

    The working you showed was actually using FOIL method, right?
    You'll have to show how to evaluate the expression by subtracting the parts from the bigger square. Please key in the working in this SAME post.
