Question

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

3, -13, and 5 + 4i

Urgently need help

Answer 1

since complex roots come in pairs, we have
(x-3)(x+13)(x-(5+4i))(x-(5-4i))
(x-3)(x+13)((x-5)-4i)((x-5)+4i)
(x-3)(x+13)((x-5)^2+4^2)
(x^2+10x-39)(x^2-10x+41)
x^4 - 98x^2 + 800x - 1599

Answer 2

Thanks
