I always like to share with my students what each Math topic has to do with their everyday life, particularly their future.
Yesterday, I did Binomial Expansion. It’s about finding the RIGHT partner (: It’s about mastering the skills of finding the correct match based on a set of factors.
Just like this question, you see that there are 2 brackets. 1st bracket is good for now. 2nd bracket needs us to do some expansion work by using the FORMULAE (It’s provided during GCE O Level Exams but some schools don’t seem to provide it for their mid year, strange)
Oh yar, there is NO need to remember the Binomial Expansion Formulae!
Then one of the questions that often pop up is ” When do we stop our expansion for 
?”
To answer this question, it depends on what type of partners you are looking for.
