@Jane_Doe- :   Please do NOT provide answers!  Guide the other person through the work needed to arrive at the solution himself/herself.

@annalea:   Please post each question separately.  Please note that it's against OpenStudy rules to just troll for answers.  Please show your own work; someone will then most likely respond with helpful suggestions.

anonymous · Answer

well I'm not "trolling" but okay.

mathmale · Answer

I'd suggest you look up some good examples of trinomials and "completing the square."  After you've done that, and after you've shown some effort, I'd be happy to help you.
