1. The problem statement, all variables and given/known data I was wondering how people intuitively see how to decompose functions? For example: x^2 + 5x - 14, how do you solve that to be (x+7)(x-2) without a calculator? Do you use a specific method or do you just sit for a while trying and failing? The question is a bit stupid, but were wondering if there is a formula or a simple method that Im missing?
