I was asked by a student to demonstrate how to factorise so of course I sent over a video showing how this is done! It was unrehearsed, done ‘on the fly’ so I am thinking the problem through but also trying to explain how I approach problems like this.
This is taken from the Edexcel GCSE Maths Higher Student Book, which I recommend for its clear text and many worked problems.
Within this video, I’m trying to show how I ‘feel’ my way through factorising trickier expressions. It’s one of those things that come with practice!
