The only root of x^3 - 6x^2 + 12x -8 is 2 and that seems to contradict the fundamental theorem of algebra, which says there should be 3

roots for a cubic function. How do you explain the difference in the number of roots?

A. There are 3 roots but 2 of them are complex.
B. There are 3 unique roots and you just haven't found all of them.
C. The fundamental theorem of algebra only states that there is a maximum of 3 roots for a cubic polynomial, so there could be 1.
D. The fundamental theorem of algebra counts each repeated root as a different root, so there are 3 roots but only 1 unique root.
