Find the Zeros of the Polynomial Function and State the Multiplicity

Find the zeros of the polynomial function and state the multiplicity of each.
- $$f ( x ) = x ^ { 3 } + 8 x ^ { 2 } - x - 8$$

A) $- 1$ , multiplicity $1 ; 1$ , multiplicity $1 ; 8$ , multiplicity 1
B) $- 8$ , multiplicity $2 ; 1$ , multiplicity 1
C) $- 8$ , multiplicity $1 ; - 1$ , multiplicity $1 ; 1$ , multiplicity 1
D) $- 8$ , multiplicity $1 ; - 1$ , multiplicity 2
