Factor Theorem and Factorising and solving Cubic equations

A quick recap of factorising standard quadratics reminds students of GCSE factorising and then goes onto introduce the factor theorem.

Several questions with answers on proving factors using the factor Theorem.

Then examples on how to use the reverse box method to do algebraic long division - by far the most fool proof and student friendly way of doing it - this is followed by a number of exercises which applies both the factor theorem to find the first root, and then using the reverse box method to factorise fully and solve.
