find all zeros of the following function:
f(x)=x^3x^2+4x4
I have (x^2+4)(x+1)
so one zero is 1. how do i find the two other zeros.

if +1 is a zero, (x1) is a factor because (x1) is zero when x = 1

I have
(x^2+4)(x1)
then when is (x^2 + 0 x +4 )= 0??
x = [ 0 +/ sqrt (0 16) ] / 2
x = +/ 2 i (imaginary roots)
