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 + 5i

Answer 1

(x - 4)*(x +8)*(x + 2 - 5i)

Answer 2

in order to have a real zero you must have the conjugate of the unreal zeros.

Answer 3

then

Answer 4

@Fgcbear16
x = -8
x + 8 = 0 NOT x-8 =0

Answer 5
