    ok, I will tell you that: 3x³ = 3x • x² 12x = 3x • 4

    I know why I am here, to help people and not to give them answer. They maybe don't realize, but they won't have openstudy for their non-online tests. Also, I don't really see a single reason for why I shouldn't be ok.

    Just imagine yourself totally unprepared for an exam..... there is a way to prevent that, you know.

    I won't further overwhelm on you though, I don't see how my talking right now can be any useful.... good luck, do well!
