This Difference of Two Squares worksheet focuses on the concept of factorising algebraic expressions that are in the form of a² - b² and is an important tool for helping students develop their algebraic manipulation skills.

The problems range from simple expressions to those where a common factor must be taken out first and even expressions where the terms inside the brackets have a coefficient different to 1 or -1. There are sixteen questions over two sections and an extension too.
