question 170

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 \(- 1 , \pm \sqrt { 7 } i\)
