## Difference of Two Squares Practice

Difference of two squares maths worksheets and answers. Difference of two squares worksheet 1 asks students to simplify the expressions in the first set of questions. The second set of questions factorise the quadratic expressions using the difference of two squares. Difference of squares worksheet 2 is an easier exercise factorising using the difference of two squares method.

## Difference of Two Squares Examples

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.
