x squared + 7x + 2x + 14? I forgot, do you add the 7 and the 2 and square the x or just leave the x and don't square it?

x squared + 9x + 14
then you have to simplify like this:
(x+7)(x+2)

Yes, add the 7 and the 2 but don't square the x on those terms. You would square the x if you were multiplying.
Think of it this way: If you add 7 cookies and 2 cookies you get 9 cookies, not 9 cookies squared.

It would be
X squared + 9x+14

X^2 + 7X + 2X + 14
another way group (X^2 + 7X) + (2X + 14)
take out X from the 1st set and 2 from the second
X(X + 7)+2(X+7) then take out (X+7)
(X+7)(X+2)

Yes - combine like terms. 7x and 2x are like terms, therefore you can add them to get 9x.
(note to some of you -- she asked a specific question about what to do with the 7x and 2x. She didn't ask you to solve the entire thing for her)

x (squared) +9x + 14 = add the middle two first...thats all you can do to simplify that......factoring is another story though.
