Question

help with factoring???!?!!

Answer 1

yes

Answer 2

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

Answer 3

and explain how you get your answer!!
the answer is supposed to be (x+7)

Answer 4

Hi, do you know your quadratic equation?

Answer 5

what do you mean ?...
:P
that's all the question says.

Answer 6

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

Answer 8

I am sorry I am running out of time, but I will try to come back in a couple of minutes.

Answer 9

I can guide you through the process easily.

Answer 10

okay, thanks! i'll wait :)

Answer 11

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?

Answer 12

2 and 7? :P

Answer 13

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

Answer 14

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.
