Answer 1

If you go to http://www.wolframalpha.com

and type

solve 0 = 3x^2 + 18x + 22

then click "show steps" it will show you how to complete the square.

If you instead type

quadratic formula

It will give you three little boxes into which you can type the a , b, and c terms. :)

Hope this helps.
