WebFactorising. Factorising is the opposite process of expanding brackets. A factorised answer will always contain a set of brackets.. To factorise an expression fully, take out the highest common factor (HCF) of all the terms. For example, \(2x\) is the HCF of \(4x^2\) and \(6x\) as 2 is the biggest number that will divide into 4 and 6 and \(x\) is the biggest term … WebThe equation factorises to give \ ( (x – 3) (x – 3) = 0\) so there is just one solution to the equation, \ ( x = 3\).
