one factor is -1, and another is 2. I used synthetic division to get these numbers, I actually don’t remember how to do possible rational zeros (PRZ’s) but with that, you get these two numbers.

Once those are factored out, the equation is (x+1)(x-2)(x^2+2x+2)=0

and the other solution is imaginary cause using the quadratic formula, the solution is :

(-2 +/- (sqrt (-4))/2 = (-1+ i) or (1-i)
