What we did in 2 hours:

This week, we started our first lesson on Expansion and Factorisation. Recall that expansion is to remove brackets from the algebraic expression and factorisation is simply the reverse, that is to create brackets. You may need to regroup the terms before you can take out any common factors for factorisation.

 

Most importantly, do memorise these three SPECIAL FORMULAE:

  1. (a + b)2= a2 + 2ab + b2
  2. (a – b)2= a2 – 2ab + b2
  3. a2 – b2 = (a + b)(a – b)

 

What you take home:

Do remember to complete the selected Take Away Questions on Expansion and Factorisation.

 

Special Mention:

We will be learning 3-term Factorisation in next lesson. A short test on Expansion and Factorisation will be conducted at the end of the lesson.

 

Till then, enjoy your CNY break! 🙂
