Need some help? … Web1.7 Factorisation (EMAG) Factorisation is the opposite process of expanding brackets. For example, expanding brackets would require 2 ( x + 1) to be written as 2 x + 2. Factorisation would be to start with 2 x + 2 and end up with 2 ( x + 1). The two expressions 2 ( x + 1) and 2 x + 2 are equivalent; they have the same value for all values of x.
