What is factorisation and how do you do it?

Factorization or factoring consists of writing a number or another mathematical object as a product of several factors,

Factorisation is basically where you have to find everything in common between 2, 3 or 4 terms.

In factorization, you take out the like-terms. eg.

12x-6y

6 (2x-y)

We have to find the HCF of 6 and 12 which is 6.

Here, the 6 is common (goes outside the bracket) and the other numbers (which are in the bracket) are uncommon.

Always remember in factorisation that:

+ and + = -

- and - = +

- and + = -

+ and - = -
