    Re: polynomials need ASAP

    A third degree polynomial takes the form: P(x) = a(x - r_1 )(x - r_2 )(x - r_3 ) where the r's are the zeros. Can you finish?

    Re: polynomials need ASAP

    but what do you do with the point? my teacher only showed us how to do it in the (...)(...) format not with three of them

    would this be right? p(x)=2(x-1)(x-2)(x-3)

    When you plug in 4 for x, do you get 12 for p(x)? If you do, then you got it!
