And that's why students are so desperate for a set of steps. Guessing and checking is how they solved linear equations before they learned algebraic manipulation.
But, I think we don't impress upon them enough that:
x²+4x-60=0
Isn't a linear equation. It's a roadblock. The linear toolbox fails. We need to find a way to make it linear again.
But even once I understood *why* they wanted a "method" I still found the idea of methods ... annoying. 4/
