[S2 Maths + Science PMCians]
What we did in 2 hours:
This week, we start off the lesson with solving CUBIC equations (ie, x to the power of 3 functions). We used the reverse of the factor theorem and the skills of comparing coefficients to fully factorise cubic equations before we solve it. The idea behind this type of question is simple but do remember to use your calculators to check your answers! 🙂
We also spent some time looking at the small extension that tags along with this type of question. We learnt how to use the factorise cubic equation to solve other equations. It was fun and exciting as students try to see the “link” between the 2 functions.
After we covered all the essential concepts in Polynomial, we spent the remaining time looking at Challenging Questions (exam standard). Through these challenging questions, students will be able to see the difference in standard questions and exam questions. Be mentally prepared for Sec 3 in 2021!

Should you need assistance in your daily practices, do send your attempted workings and questions to 9005 1733. We will strive to clarify your doubts.
This is a gentle reminder for students who score below 70 are required to send in your papers for your tutors to review so that we can work on the areas to be improved on in 2021.
See you in class!
