KS4 Higher Quadratic Formula

This set of resources provides resources that introduce, prove, worked examples, and questions of the quadratic formulae. All resources use a graphical method that emphasise to the student that they are finding the roots of the equation and that some curves do not cross the horizontal axis and hence no roots can be found.

A video introduction is used from youtube that has no advertisements and gives a steady but detailed introduction using worked examples without any proof.
