Question

Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in standard form.

4, -8, and 2 + 3i

f(x) = x^4 - 6x^3 + 12x^2 - 90x + 416

f(x) = x^4 - 45x^2 + 180x - 416

f(x) = x^4 - 35x^2 + 180x - 416

f(x) = x^4 - 6x^3 - 12x^2 + 90x - 416
