Expand further algebraic expressions
Lesson

We've learnt a number of techniques for expanding and simplifying algebraic expressions. Being familiar with the addition, subtraction, multiplication and division of algebraic terms, and having experience in expanding binomials, perfect squares and expressions resulting in the difference of two squares, means we can begin to work with some more complicated expressions.
