As part of my degree in physics with Astrophysics, I have to do some maths modules. In the maths lectures, the lecturer just goes though a giant 212 page work booklet explaining everything as she goes along. Me and a friend only do the work booklet in the lectures and we're already on page 33 while everyone else is on page 14.(adsbygoogle = window.adsbygoogle || []).push({});

I am not sure if I have done these questions correctly (page 21), because I've never used this method of factorising polynomials before (there was an example of how to do it in the workbook)
