Algebra - Factorisation 1
Factorising an expression simply means dividing it back into brackets. It is the exact opposite of multiplying out of brackets.
First we find the Highest Common Factor (HCF)
[biggest number that goes into everything]
and write that down outside the brackets.
We then divide every term in order by the HCF
and write the results inside the brackets.
To divide an algebraic term by the HCF we do
"numbers then letters" in order.
