### Quick Reference (4)

Factorising complete squares

There is a special case of quadratic expression known as a complete square. This leaflet explains what this means and how such expressions are factorised.

Factorising quadratics

This leaflet shows how to take a quadratic expression and factorise it.
Special cases of complete squares and difference of two squares are dealt with on other leaflets.

Factorising quadratics

In this leaflet, we explain the procedure for factorising quadratic expressions. Be aware, not all quadratic expressions can be factorised.

Factorising the difference of two squares

There is a special case of quadratic expression known as the difference of two squares. This leaflet explains what this means and how such expressions are factorised.
