    quadradics with complex

    Hi, this is my last help for today. I want to thank Hacker for being so helpful.
    I also want to apologize to Hacker for double posting, I won't do it again.

    ---
    Give f(x) = x^2+6x+13 in factored form, and show that when you multiply the factors together you get f(x) in standard form.

    Help please =[

    This quadratic has complex roots.

    What two values when added equal 6 and when multiplied equal 13

    There are no reals that fit this criteria.

    (3-2i) and (3+2i)

    (3-2i)+(3+2i)=6

    (3-2i)(3+2i)=13

    (x+3+2i)(x+3-2i)
