Please post your 100- 125 word (or more) response (as an essay) to the following:

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? When might each method be most appropriate? Which method do you prefer? Explain why. You may want to use the table feature to create a neat and organized list of pros and cons.
Solve the quadratic x2 – 8x + 15 = 0 using all four methods (for the graphing part, simply describe your graph here for your classmates, or include as an attachment). Refer back to your list of pros and cons to describe the method you preferred.

Solve:
0=3x^2+6x+21
0 = 4x^2 + 6x + 4
