Factorisation by GROUPING

Post was first put up on 17 April 2020 for self-directed learning (weekend homework)



Click HERE to watch the Playlist.

Then try to factorise the following in your NOTEBOOK.


[UPDATED After lesson on 21 April (Tuesday)]
During lesson, we went through 1(a) and 4(a). We did not get the time to go through 2(a) & 3(a).

  • Fazila asked if we could re-organise the terms; 
  • Sylvester asked whether we could extract "-1" (common factor) from the first factor instead of the second one.
Both are feasible and will end up with the same answer :)
I've provided a written explanation for the questions. 
Read through and check with me if you are still not sure.
Do check this working against your own working, too.

Attempt 2(a) and 3(a). Then check your answer against the one below. 
Read through and check with me if you are still not sure.
