Nice general question.

Just translate the worded description into symbols and form the area calculation. Simplify.

Sides, a and b.
Remove x by x square from each corner.

highlight%28%28ab%29-4x%5E2=A%29----
That's it! The area before removing any x is just a%2Ab.
Each square at the corner is x%5E2, and the original rectangle piece has four of them; so removing those is -4x%5E2.
