Question 15

Multiple Choice

Write f(x) =x42x3x238x+130f ( x ) = x ^ { 4 } - 2 x ^ { 3 } - x ^ { 2 } - 38 x + 130 as a product of linear factors given that 3i3 - i and 23i- 2 - 3 i are zeros of the polynomial.


A) (x3i) (x2+3i) (x23i) (x2+i) ( x - 3 - i ) ( x - 2 + 3 i ) ( x - 2 - 3 i ) ( x - 2 + i )
B) (x3i) (x3+i) (x2i) (x2+i) ( x - 3 - i ) ( x - 3 + i ) ( x - 2 - i ) ( x - 2 + i )
C) (x3i) (x3+i) (x23i) (x2+i) ( x - 3 - i ) ( x - 3 + i ) ( x - 2 - 3 i ) ( x - 2 + i )
D) (x3+i) (x3i) (x+3+2i) (x+32i) ( x - 3 + i ) ( x - 3 - i ) ( x + 3 + 2 i ) ( x + 3 - 2 i )
E) (x3+i) (x3i) (x+2+3i) (x+23i) ( x - 3 + i ) ( x - 3 - i ) ( x + 2 + 3 i ) ( x + 2 - 3 i )
