grrrr...I hate it when these equations don't factor and I have to go through the entire quadratic formula! So irritating!

If you don't want to go through the entire quadratic equation it is often easier to just use Vieta's Formulas, though not always. Though in general I have to admit I agree with you, it is annoying having to resort to the quadratic formula.

Nah I love it when that happens (well I love math) because you can find the radical answers like 2 +/- 2^(1/2)

I would say catch yourself quicker with a negative.
