## Countdown to Exams - Day 15 - Factorising Quadratics

In today's revision countdown, we are taking a look at Factorising Quadratics. Remember, factorising is putting into brackets! It is important to remember the general structure of a quadratic as you may need to rearrange your expression/equation to create the general structure.

We start off by looking at simple quadratic expressions where the a value is equal to one. The key point to remember here is the 'Sum and Product rule' We finish off by looking to factorise quadratics where the a value is not equal to 1.

## Countdown to Exams - Day 12 - Expanding brackets

On day 12 we take a look at Expanding brackets. It is important to state that this is the inverse of factorising and we take you through the process of expanding brackets by multiplication! Once the brackets have been expanded, it is essential to collect like terms and simplify your answer otherwise you will lose marks in a test.

Here we cover expanding single brackets and move onto double brackets. Note there is more than one method so make sure you get really comfortably with a method and get those marks!
