Factorisation

Factorisation is the opposite process of expanding brackets. For example, expanding brackets would require \(2(x + 1)\) to be written as \(2x + 2\). Factorisation would be to start with \(2x + 2\) and end up with \(2(x + 1)\).

The two expressions \(2(x + 1)\) and \(2x+2\) are equivalent; they have the same value for all values of \(x\).
