In order to factorise an algebraic expression using the difference of two squares: Write down two brackets. Square root the first term and write it on the left hand side of both brackets.
What is the difference of two squares?
The difference of two squares is a method of factorising used when an algebraic expression includes two squared terms, one subtracted from the other: When we are subtracting a squared term from another squared term we can use the difference of two squares method.
How do you factor the difference of two squares into brackets?
The difference of two squares can be factorised into brackets using the method above for factorising quadratics. Factorise \\ (x^2 - 4\\). Quadratics can be factorised into the form \\ ( (x + a) (x + b)\\). \\ (x^2 - 4\\) can be written as \\ (x^2 + 0x - 4\\).
How to subtract a squared term from another squared word?
When we are subtracting a squared term from another squared term we can use the difference of two squares method. Square numbers are sometimes called perfect squares. An example of an expression we can factorise using the difference of two squares might be x 2 – 4 or 4x 2 – 25
