For many Secondary 3 A-Maths students, this topic called Factor - Remainder theorem or Polynomials is usually introduced in the first 3 months of the year.
In this topic, they are introduced to the method to find the factors of a cubic equation so that it can be solved. They also learnt when and how to use Remainder theorem to find the remainder when a dividend is divided by a divisor.
They also know to rewrite an expression into function f(x).
In the following two videos, I use less than 6 minutes to bring across the concepts of Factor theorem and Remainder theorem.
I hope through these videos, you will have a better understanding of these two concepts.
Also, I have included a page which contains all the O-Level Maths videos I have produced since 2007.

Hi, I'm Ai Ling Ong. I enjoy coaching students who have challenges with understanding and scoring in 'O' Level A-Maths and E-Maths. I develop Math strategies, sometimes ridiculous ideas to help students in understanding abstract concepts the fast and memorable way. I write this blog to share with you the stuff I teach in my class, the common mistakes my students made, the 'way' to think, analyze... If you have found this blog post useful, please share it with your friends. I will really appreciate it! :)
A clear and precise explanation.
It would be great if some challenging examples can be included.
Thank you.
