    Yet another dumb question (zeros of a cubic function)

    f(x)= x^3-2x^2-11x+52 ----> Find all of the zeros of the function I just need some advice/direction on how to start solving this. It is not in the textbook and my brain is just kinda farting when I look at it. I think i need to get it in an (x-a)(bx^2+cx+d) form or something, but I don't know.

    Solving a Quadratic Equation: Finding All Linear Factors

    And that, my friend, is why my name is DumbKid. Ya -3 +4 surely is not -1. Thanx for the help.

    Solving a Quadratic Equation: Finding All Linear Factors

    Ok this should be pretty simple math for you guys (Sophomore in HS) Given that x-2 is a factor of P(x)=2x^3-3x^2-17x+30, find all other linear factors. I started out doing synthetic division, and got 2x^2-x-19 with remainder -8. Shouldn't the remainder be zero since x-2 is a factor...
