1.This week, we covered our math EOY revision on the topic of algebra. We revisited the important areas regarding expansion & factorisation of algebraic expressions. 1) Take note of the common mistakes we have identified regarding expansion & factorisation. 2) Remember the importance of brackets after expanding & factorising when there exist a negative sign. 3) Follow the SOP that we have covered in approaching the various types of factorisation problems, always try looking out for common factor first before moving on to the next step of factorising.
