About this lesson
This is the first video in a series looking at algebraic techniques which forms a part of the Year 9 Mathematics course. Looking at expanding binomial products, this is the start of building knowledge and skills to help us factorise quadratics (trinomials). I look at how we can expand brackets and use a number of examples to complement the easy to understand theory.
