Question 376

Multiple Choice

Find a polynomial of least degree with only real coefficients and having the given zeros.
- −3,3- \sqrt { 3 } , \sqrt { 3 } , and 8 (multiplicity 2 )


A) f(x) =x4−16x3+61x2+48x−192f ( x ) = x ^ { 4 } - 16 x ^ { 3 } + 61 x ^ { 2 } + 48 x - 192
B) f(x) =x3+8x2−3x−24f ( x ) = x ^ { 3 } + 8 x ^ { 2 } - 3 x - 24
C) f(x) =x3−8x2−3x+24f ( x ) = x ^ { 3 } - 8 x ^ { 2 } - 3 x + 24
D) f(x) =x4+16x3−61x2−48x+192f ( x ) = x ^ { 4 } + 16 x ^ { 3 } - 61 x ^ { 2 } - 48 x + 192
