# Factorising Expressions

Students learn how to factorise algebraic expressions using the highest common factor and basic algebraic notation.  As learning progresses they are challenged to investigate possible perimeters for a rectangles with algebraic lengths.
##### Differentiated Learning Objectives
• All students should be able to fully factorise an algebraic expression in the form ax+b where a and b are both constants.
• Most students should be able to fully factorise an algebraic expression in the form ax2+bx where a and b are both constants.
• Some students should be able to fully factorise an algebraic expression the form ax2y + bxy2 where a and b are both constants.
