Algebra - Factorisation 2

Here is a simple example:

Factorise 4x + 6x²

First find the HCF "numbers then letters"

We can divide 4 and 6 by 2

We can divide x and x² by x

The HCF is simply 2x

Now divide each term by the HCF

We can always check by mulitiplying back out:

2x.2 + 2x.3x = 4x + 6x²
