Good to see all of you back after the 2 weeks break! This week marks the first lesson of headstart, where we explored the next part of your algebra journey. After a quick recap on Sec 1 algebraic expansion, we went on to look at what Sec 2 expansion has for us! Instead of a single term entering the “house” (ie, formally known as brackets), we have 2 “houses” side by side. Using our trusty rainbow method, we can expand all sorts of expressions with patience and practising due diligence to ensure all terms are accounted for at the last line. Moving into the 2nd hour, we were introduced to 3 efficient shortcuts, namely: (i) (a+b)^2 = a^2 + 2ab +b^2 (ii) (a-b)^2 = a^2 – 2ab +b^2 (iii) (a+b)(a-b) = a^2 – b^2 These shortcuts enable us to tackle expansion questions with much more speed. As mentioned in class, the speed will come after much practice. So, have you tried the Take Away Questions on page 22 to 26 ? – please do so before you attend this coming lesson.Buy Now !
