This is a must to have set of resource for A level pupils and the higher GCSE pupils. The topic is covered in three lessons. The first two lessons provide a 'supersonic,' technique for finding the roots of a cubic equation/function and the third lesson will demonstrate an easy to follow step by step method of finding the roots of a cubic equation/function by trial and error. I strongly recommend the user of tese three lessons to also look at another of my lessons on the division of polynomials published on tes in order to enhance their ability to fully benefit from these three important lessons. Generally finding the roots of cubic equations/functions is a very hard task howe ver the method which I have shown in these lessons will demonstrate how easy and quickly these roots can be found but this method is not contained in any text book that is available to the user.
