    Here's the question: Determine the missing factor.. 1. \[x ^{2} + 9x + 14 = (x+2) (?) \]

    Hmm.. If you have not learned the quadratic equation yet, let's try the box method.

    x^2 +9x+14=(x+2)(?) So for this problem let's just look at this portion first: (x+2)(x+?) Let's ignore the x's and call 2 a, and ? b. What we want to know here is b. Here are some clues that can help you. Added together, A+B = 9. Multiplied together, A*B = 14. Can you tell me what numbers I am look for?

    so it's (x +2) (x + 7) ?

    That is right on! Yes, remember that the a and b have to ADD to the middle term, the bx in the equation. And a and b have to MULTIPLY to the end term or the constant.
