In order to expand and simplify an expression, we need to multiply out the brackets and then simplify the resulting expression by collecting the like terms.

Expanding and simplifying. Expressions can be expanded by removing brackets and then simplified by adding / subtracting like terms as required.

There are a number of methods used to simplify and expand two brackets. We will explore four methods and you can choose a method that works for you.

Algebraic expressions can be expanded - multiplied by one or more terms. They may also be simplified – made shorter and simpler by collecting like terms.

To expand an algebraic expression, use the distributive property. This means to multiply the term outside the parentheses by each term inside the parentheses.

Expanding an algebraic expression allows you to change the form of an expression without changing the output values it gives.
