Simple Factoring Problem

I know this isn't a tough problem, but I am having a complete disconnect from how it can be factored given what I know about factoring. I know it is a trinomial with a leading coefficient besides 1, thus I can use the AC method, but I don't see what numbers would help me build my 4 terms to continue factoring. My humblest thanks on this problem. If anyone could explain how and what the next steps are I would be humbled. I used MathPapa and Symbolab on this problem which were helpful with the solutions, just not the why.

$2x^2+x-1$

Thanks tkhunny

Thanks You do know that there isn't a good definition of "tough problem", right?

There is only one way to Factor that "2" and only one way to factor 1.
