question 98

Multiple Choice

Write the polynomial in standard form and identify the zeros of the function.
- $$f ( x ) = x ( x + 3 ) ( x + 2 - i ) ( x + 2 + i )$$

• A) \(f ( x ) = x ^ { 3 } + 7 x ^ { 2 } + 17 x + 15\); zeros \(- 3 , - 2 + i , - 2 - i\)
• B) \(f ( x ) = x ^ { 4 } + 7 x ^ { 3 } + 15 x ^ { 2 } + 9 x\); zeros \(0,3,2 + i , 2 - i\)
• C) \(f ( x ) = x ^ { 4 } + 7 x ^ { 3 } + 17 x ^ { 2 } + 15 x ;\) zeros \(0 , - 3 , - 2 + i , - 2 - i\)
• D) \(f ( x ) = x ^ { 4 } + 7 x ^ { 3 } + 17 x ^ { 2 } + 15 x\); zeros \(0 , - 3,2 + i , 2 - i\)
