2.2.2 Simple Factorisation

What is simple factorisation?

Simple Factorisation is the opposite of Expanding One Bracket

Beware of minus signs

Remember the basic rules:

“ − × − = + ”

“ − × + = − ”

How to factorise

  • Write each term in factorised form
  • Identify the common factors
  • Write those factors outside a bracket
  • Write everything else inside the bracket
    You can check your answer by multiplying out (in your head!)
