# Factorising Quadratics ax^2 + bx + c

Students learn how to factorise quadratics in the form ax2 + bx + c involving positive and negative terms into two brackets.  As learning progresses they consider non-prime coefficient of x2.
##### Differentiated Learning Objectives
• All students should be able to factorise a quadratic where the coefficient of x squared is a prime number and the constant is a positive integer.
• Most students should be able to factorise a quadratic where the coefficient of x squared is a prime number and the constant is a positive or negative integer.
• Some students should be able to factorise a quadratic where the coefficient of x squared is a non prime number and the constant is a positive or negative integer
