How to factorise linear equations

Factor linear expressions

Example 1 - Factorising simple linear expressions a) Factorise: 3 x + 9. Notice 3 is both a factor of 3 x and 9. We can factorise the expression by taking the 3 outside of the brackets. Factorising an expression is to write it as a product of its factors. There are 4 methods: common factor, difference of two squares, trinomial/quadratic expression and completing the square.

Factoring is a method that can be used to solve equations of a degree higher than 1. This method uses the zero product rule. If (a)(b) = 0, then. Either (a) = 0, (b) = 0, or both. Example 1. Solve x(x+ 3) = .
