Write the Polynomial in Standard Form and Identify the Zeros $$f ( x ) = ( x - 1 ) ( x - \sqrt { 7 } i ) ( x + \sqrt { 7 } i )$$

Multiple Choice

Write the polynomial in standard form and identify the zeros of the function.
- $$f ( x ) = ( x - 1 ) ( x - \sqrt { 7 } i ) ( x + \sqrt { 7 } i )$$

A) $f ( x ) = x ^ { 3 } - x ^ { 2 } + 7 x - 7 ;$ zeros $1 , \pm \sqrt { 7 } i$
B) $f ( x ) = x ^ { 3 } - x ^ { 2 } - 7 x + 7 ; \operatorname { zeros } 1 , \pm \sqrt { 7 } i$
C) $f ( x ) = x ^ { 3 } - x ^ { 2 } + 49 x - 49$ ; zeros $1 , \pm 7 i$
D) $f ( x ) = x ^ { 3 } - x ^ { 2 } - 7 x + 7 ;$ zeros $- 1 , \pm \sqrt { 7 } i$
