Multiple Choice

Find a polynomial of least degree with only real coefficients and having the given zeros.
- 3,113 , - 11 , and 4+4i4 + 4 i


A) f(x) =x465x2+520x1056f ( x ) = x ^ { 4 } - 65 x ^ { 2 } + 520 x - 1056
B) f(x) =x4130x2+520x1056f ( x ) = x ^ { 4 } - 130 x ^ { 2 } + 520 x - 1056
C) f(x) =x47x3+12x2260x+1056f ( x ) = x ^ { 4 } - 7 x ^ { 3 } + 12 x ^ { 2 } - 260 x + 1056
D) f(x) =x47x312x2+260x1056f ( x ) = x ^ { 4 } - 7 x ^ { 3 } - 12 x ^ { 2 } + 260 x - 1056
