x^2-12x+45
___
x+1 | x^3-11x^2+33x+45
- (x^3+x^2)
-12x^2+33x+45
- (-12x^2-12x)
45x+45
-(45x+45)
0
Since that works, it's either B or D. We just have to figure out when
x^2-12x+45 equals 0, since there are 3 roots and we already found one. Using the quadratic formula, we end up getting (12+-sqrt(144-180))/2=
(12+-sqrt (-36))/2. Since sqrt(-36) is 6i, and 6i/2=3i, it's pretty clear that B is our answer
