Collecting Like Terms

Collecting like terms generally means simplifying an algebraic expression having mutliple terms.

This means we are grouping ‘like terms’ together and performing whatever operation needs to be performed on them.

For example expression 3x + 4x – 2x simplifes to just 5x. Below are some examples that explain all this, starting with a short video.

Sometimes you need to perform a step before collecting like terms such as if your expression contains brackets. In this case you must expand brackets first before atempting to collect like terms.
