okay, do you know how to factor quadratics?

anonymous · Answer

I think the answer is (3z - 1) ( 2+5)
it's one of those beginning quizzes and based off of how well I do on it I could have less work or more work todo so I'm trying to get alll of them right so that hopefully I don't have so much to do before graduation =o

bloomlocke367 · Answer

well, if you expand that, and you get the right answer, then it's correct.

bloomlocke367 · Answer

however, I can already tell you it's wrong...

anonymous · Answer

do I have it backwards or..

bloomlocke367 · Answer

with what you have, the leading term would not be squared.

anonymous · Answer

I'm confused =/ I'm really not great at math I just found a site that helps me work it out and this is what it came out to =o

anonymous · Answer

(z+5)(3z−1)

bloomlocke367 · Answer

that gives you $3z^2-z+15z-5$ which is $3z^2+14z-5$ so it's correct. would you like me to show you how to get that?

anonymous · Answer

sure =)

bloomlocke367 · Answer

okay, it's a little bit more complicated since the leading coefficient is not 1.

bloomlocke367 · Answer

so first, you have to see if there's a GCF (greatest common factor)

bloomlocke367 · Answer

do you see a gcf in your equation?
