What is simple factorisation?

Simple Factorisation is the opposite of Expanding One Bracket. 

Beware of minus signs

Remember the basic rules:

“ − × − = + ”

“ − × + = − ”

How to factorise

  1. Write each term in factorised form.
  2. Identify the common factors.
  3. Write those factors outside a bracket.
  4.   Write everything else inside the bracket.

You can check your answer by multiplying out (in your head!).
