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.

A clear and precise explanation.

It would be great if some challenging examples can be included.

Thank you.
