Quadratic equations may be solved by graphing, using the quadratic formula, completing the square, and factoring.
What are the pros and cons of each of these methods? Please provide examples.
When might each method be most appropriate?
Which method do you prefer? Explain why.

Completing the square IS the quadratic formula as far as I am concerned, just that plugging into the formula is faster than going through the derivation every time.
Graphing is slow and not so accurate.
If it can be factored using whole numbers, that is fastest and easiest.
I use
1. factors
2. If I can not find factors immediately, use quadratic equation.
