SOLUTION: I don't get how to find the zeros or what the x=-3 is for.
f(x)=x^4+2x^3-13x^2-38x-24 and one x=-3? All zeros are needed to be found.

Answer by checkley75(3666) (Show Source): You can put this solution on YOUR website!
F(-3)=(-3^4)+(2*-3^3)-(13*-3^2)-(38*-3)-24
F(-3)=81-54-117+114-24
F(-3)=81+114-54-117-24
F(-3)=195-195
F(-3)=0 ANSWER.
