# Math Help - Factoring problem (should be easy =\ )

1. ## Factoring problem (should be easy =\ )

Hi, this is my first post. I am doing algebra for the first time in a decade and I am having trouble working this out. I've tried a few different ways and I know it is easy but I just can't get it =\

Factor the following expression:

$x^2 - 4 + (x+2)^3$

What am I missing?

Substitute x^2 - 4 = (x - 2)(x + 2). Then factorise by taking out the common factor of (x - 2). Check for further simplification after doing this.
