factor x^3 + 3x^2 + 3x + 2

Reiny
x^3 + 3x^2 + 3x + 2
let f(x) = x^3 + 3x^2 + 3x + 2
f(1) = 1+3+3+2 ≠ 0
f(1) = 1 + 3  3 + 2 ≠0
f(2) = ..... ≠ 0
f(2) = 8 + 12  6 + 2 = 0 , so x+2 is a factor
do a long division to get the remaining quadratic factor.

I'm trying to solve x^33x^2x+3 is less than zero. Except, I'm not sure how to factor it. I tried splitting it so that 3 would be a factor for 3x^2 and 3, so the result was 3(x^2+1), and x^2 was a factor for x^3 and 3x^2, resulting …
