This is the next video in the Year 9 Mathematics series looking at Algebraic Techniques. In previous videos we have looked at how to expand brackets and binomial products. We have looked at basic factorisation and how to factorise DOPS. This video scaffolds the rest of the work in this section and shows how we can start to build the knowledge and understanding of how to factorise quadratic trinomials. I look at how we can use factorising by grouping to turn four terms into two and then into a binomial product. There are lots of worked examples and all are explained in an easy to understand way.
There are no current errors with this video ... phew!
