In this lesson we will look at expanding brackets to multiply irrational surd terms together, simplify surd expressions and learn about how the common "Difference of Two Squares" surd bracket expansion can rationalise a surd expression

This is out fourth lesson on surds, so if you missed the first three lessons you will need to see them first.
