Difference of two squares worksheets and answers. Difference of two squares worksheet 1 asks students to simplify the expressions in the first set of questions. Difference of two squares worksheet 2 contains a set of questions on factorising the quadratic expressions using the difference of two squares. Difference of squares worksheet 2 is an easier exercise for factorising using the difference of two squares method.

Why Is It Called Difference of Two Squares?

Quadratic equations have highest order of 2 (x2). There are four main ways to solve quadratic equations: factorising, quadratic formula, graphical method and completing the square. Some quadratic equations can be factorised using the difference of two squares. The difference of two squares takes the form a2 - b2 = (a + b)(a - b).

How To Solve Difference of Two Squares

When solving quadratic equations by difference of two squares we factor into the form (a + b)(a – b). For example x2 - 25 = (x + 5)(x - 5), x2 - 16 = (x - 4)(x + 4), 4x2 - 144 = (2x - 12)(2x + 12), and so on. Below contains four examples of factorising the difference of two squares.
