About this lesson
This is the final video in the series on Polynomials for the Year 11 Mathematical Methods course (VCE Units 1 and 2). I take time to look at how we can use something called the Bisection Method to find the roots of polynomials through a guess and check type way. Looking at intervals and finding midpoints, we can quickly and easily find decimal roots of polynomials. I also look at the Pseudocode which can be used to describe and simulate the Bisection Method shown in the video. I look at one example in depth and another which could be quite tricky. All is explained in an easy to understand way.
