(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A part of a problem is to factor 8 - b^3

"8 minus b cubed"

2. Relevant equations

3. The attempt at a solution

I see that the problem is 2^3 - b^3.

I don't see the next step

I know the answer is (2-b)(4+2b+b^2).

but I can't get there.

Is this just trail and error dividing terms into the polynomial or is there a more obvious solution?

Thanks
