Description

This is the next video in the Algebraic Techniques section of the Year 9 Mathematics course. Having looked at how to expand binomial products which gave Difference of Perfect Squares (DOPS) results, we now look at how we can factorise DOPS. We look at a lot of examples of how to factorise using DOPS including some quite challenging questions. The examples are all framed by easy to understand explanations. There is even some humour!
