Linear and simultaneous equations
Essential Mathematics Year 9
This is the third video in the Year 9 Algebra series of videos. Expanding algebraic expressions is a really important skill to learn and can be quite simple (to start with) but it is filled with tricks and relies heavily on your ability to collect like terms and multiply algebraic terms together. With practice you can get really fast at doing this as it's important for many of the topics we will cover in Year 9 and beyond. I explain how to do it and then use lots and lots of worked examples to try and help you smash this topic
