Try out Part 4 of our “How to” Algebra guides. This week covers factorising quadratics, which means “putting it into 2 brackets”.
The standard format for quadratic equations is
This guide will show you methods of factorising when ‘a’ = 1, and when ‘a’ is not 1 (which is a bit trickier!). It will also take you through how to solve quadratic equations after factorising them.
There are some example questions for you to measure your progress, and answers are provided for you to check your understanding.
