Description
This is another in the Year 9 series looking at Algebraic Techniques and, importantly, how to expand brackets and factorise a range of expressions. This video looks at how we can build on the previous knowledge and start to factorise quadratic trinomials. I use the idea of the 'T' method to factorise any quadratic trinomial. There are lots and lots of examples and all are explained in an easy to understand way.
