(3) Chap 5: Watch the video... Factorisation by Grouping

Factorisation by Grouping: Look out for the approach!
  • Taking the terms by pairs first.
  • Identify the common factor between the 2 terms first.
  • Then carry out the same process - identify the common factor before putting the rest together.
  • The video also shows you that the same answer is obtained even if you re-organise the terms (sometimes)
