I love this topic! This is another video relating to Polynomials; a part of the Year 10 Mathematics course. Mind you, this also features heavily in Year 11 and Year 12 too! I look at how we can applying the learning we had from FOIL and Quadratics, to brackets with more than two terms. I give examples of not only how to expand quadrilaterals but how to simplify them like a boss! There are lots of worked examples and I explain the theory in an easy to understand way!
