sum and difference of two cubes

approaching this numerically is slow...
students will need to be able to form a quadratic general rule after a factor has been extracted for their results
with, probably, a few other examples

















it may be advisable to move on to a understanding a geometric interpretation and then return to generalisations for the forms of these questions later
