Form a polynomial f(x) with real coefficients having the given degree and zeros.Degree: 5; zeros: 2, -3i, and 4 - i
A. f(x) = x5 - 10x4 - 42x3 -124 x2 + 297x + 306 B. f(x) = x5 - 10x4 + 26x3 -124 x2 + 72x + 306 C. f(x) = x5 - 10x4 + 26x3 -124 x2 - 72x - 306 D. f(x) = x5 - 10x4 + 42x3 -124 x2 + 297x - 306
