This final video in the series looks at how we can use all the learning from the previous videos to help us factorise cubics using polynomial division and then sketch them. The video looks at what the more popular polynomials looks like (cubic and quartic) and then how we can plot their respecting points to see what the graphs look like. I then move on to look at the positive and negative cubics and how we can use algebra to find the crossing points on the x-axis and y-axis to sketch a pretty good representation. I look at how to use the CAS to sketch and interrogate polynomials as well as how to come up with the equation from a graph. There are a number of worked examples and the theory is explained in an easy to understand way.
