#### Home / Interactive Lessons / Algebra / GCSE / Year 9 Term 2

Students learn how to factorise quadratics in the form x2 + 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 ax2+bx+c where a = 1 and both factors are positive.
• Most students should be able to factorise quadratics in the form ax2+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.
