Learning objectives

At the end of this chapter you are able to...

...use the distributive law to expand and simplify brackets.

...expand and simplify (a+b)(c+d)

...expand  perfect squares like (a+b)²

...expand the difference of two squares like (a+b)(a-b)

...expand more complicated algebraic expressions. 

...expand radical expressions. 

Explanation videos

Basic expansion 

In this video you will learn how to expand brackets. You do not need any prior knowledge since this video will teach you the basics. 

The expansion of perfect squares & the difference of two squares

In this video you will learn how to expand brackets in the form(a+b)(c+d) and (a+b)² and (a+b)(a-b). You do need prior knowledge for this video since you need to have knowledge about expanding brackets.  

Expand more complicated algebraic expressions

In this video you will see some examples about expanding and simplifying more complicated expressions. Mixed expressions, expressions with radicals, expressions with multiple brackets are seen as more complicated expressions. 

Expand radical expressions (square roots)

In this video you will learn how you can expand brackets with square roots. You will learn the basics as well in case you forgot.
