    Good!!

    But I am a dunce and wasn't paying enough attention. TheOwne is right. This one doesn't factor nicely so using the quadratic formula is your best bet.
    Sorry about that. You factored out the nine really nicely though!

    but our teacher says that we need to factor it, we are almost done with this chapter, and we havent used the quadratic formula in it. he just told us that if it "cant be factored" you just dont solve it and you write "cant be factored"... so that cant be factored? so i just write cant be factored to satisfy my teacher for now?

    Yep,

    ORIGINALY POSTED BY TheOwne
    Have you learned the quadratic formula? If you can't do it simply, then you can use the quadratic formula.



    But you can't do that here because b^2-4ac gives you a negative value, which you can't take the square root of..

    ..so there's no roots for this...
    There are no roots as TheOwne said. So yeah, it isn't factorable. I guess unless factoring out the nine was all that your instructor wanted. Cause that is as far as it goes.
