Quadratic expressions can be written in the form ax²+bx+c, where a, b, and c are numbers. When factoring quadratic where x² has a coefficient of 1, students simply need to think of two numbers that add to give the coefficient of x and multiply to give c. This method will not work when factorising quadratics where the coefficient of x² is greater than 1, therefore students will learn to apply a new procedure to factorise such quadratics.

In this class, students will understand what is meant by the coefficient of x², how to factorise quadratics using number manipulations, and how to expand brackets to check if the factorisation was correct. This class is aimed at Years 9 - 11.
