Learn how to write Quadratic Expressions in Completed Square form
Quadratic expressions can be written in different formats for different purposes. The completed square form can be used for particular purposes, but sometimes it’s just a stand-alone algebra technique. When algebra students start working with quadratic expressions (i.e. one which contains an x-squared term) they are soon expected to be able to perform completing the square.

Completing the square is a type of factorising for quadratic expressions
You must learn what the completed square form looks like
There are two methods of completing the square – one basic and one more complex
The basic form should be a one step process
With a number in front of the X squared term the working is trickier
