Solve. 10x^2 + 3x + 9

OpenStudy (maddy1251):

What are you solving for? Factoring? Finding 'x'?

OpenStudy (anonymous):

Yes, factoring could you help please?

OpenStudy (maddy1251):

Sure thing.

OpenStudy (anonymous):

Okay thank you so much Maddy.

OpenStudy (maddy1251):

You're welcome, just give me a second :-)

OpenStudy (maddy1251):

\[10x^{2}+3x+9\]

OpenStudy (anonymous):

Yes that's the equation. Don't I add 3x to both sides of the equation?

OpenStudy (maddy1251):

When you factor a polynomial, you want to find common factors to put it into the form of (x+a)(x+b). If factoring is what you're doing

OpenStudy (maddy1251):

We know to get the leading coefficient, we need to multiply 5x and 2x together. (5x )(2x )

OpenStudy (anonymous):

So like it's laid out like this: \[10x ^{2}+3x+9+3x?\]

OpenStudy (maddy1251):

I'm not really sure how you got that.

OpenStudy (maddy1251):

We are factoring to form two binomials to create the polynomial

OpenStudy (anonymous):

Wait so it's the answer?

OpenStudy (maddy1251):

By any chance, do you have answer choices to this question? That way I know exactly what we are looking for.

OpenStudy (anonymous):

Because that doesn't look like the answer. I'm in 9th grade and I need a lot of polynomial help.

OpenStudy (anonymous):

No I have no answer choice.

OpenStudy (maddy1251):

Okay. And it wants the factored form, right?

OpenStudy (maddy1251):

I am assuming so since it isn't set to 0, it doesn't want to know what 'x' is.

OpenStudy (anonymous):

okay thanks for your help anyways.

OpenStudy (maddy1251):

I am working on the answer give me one minute

OpenStudy (maddy1251):

Do you know how to foil?
