What do you think the answer is?

OpenStudy (anonymous):

C?

I really have no idea..

Its B. because What two numbers multiply themselves to get 30 and add to get -12. That would be -6. Because -6+(-6) = -12 and -6*-6 = 36.

Thanks so much!

OpenStudy (anonymous):

what two numbers multiply themselves to get 36*

OpenStudy (anonymous):

6and 6

OpenStudy (anonymous):

No

OpenStudy (anonymous):

-6 and -6

OpenStudy (anonymous):

Ohhh

OpenStudy (anonymous):

so the factored form would be (x-6)(x-6)

OpenStudy (anonymous):

think what two numbers multiply to get the 3rd term and when the two numbers add they equal the 2nd term
