^{2}+ bx + c into two brackets with a mixture of negative and positive terms. As the learning progresses students begin to use the difference of two squares to factorise quadratics with a zero x term.

**Differentiated Learning Objectives**

- All students should be able to factorise quadratics in the form ax
^{2}+bx+c where a = 1 and both factors are positive. - Most students should be able to factorise quadratics in the form ax
^{2}+bx+c where a = 1 and either or both factors are negative. - Some students should be able to factorise quadratics using the difference of two squares.
