question 70

Multiple Choice

Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the
polynomial in standard form.
-2 (multiplicity 2) and $1 + 3 i$ (multiplicity 1 )

• A) \(f ( x ) = x ^ { 4 } - 6 x ^ { 3 } + 40 x ^ { 2 } - 48 x + 40\)
• B) \(f ( x ) = x ^ { 4 } + 6 x ^ { 3 } + 22 x ^ { 2 } - 48 x + 40\)
• C) \(f ( x ) = x ^ { 4 } - 6 x ^ { 3 } + 22 x ^ { 2 } + 28 x + 40\)
• D) \(f ( x ) = x ^ { 4 } - 6 x ^ { 3 } + 22 x ^ { 2 } - 48 x + 40\)
