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

anonymous · Answer

other root is $2-5i$ so your job is to multiply out 
$$(x-4)(x+8)(x-(2+5i))(x-(2-5i))$$

anonymous · Answer

the first two are easy 
you get 
$$(-4)(x+8)=x^2+4x-32$$

anonymous · Answer

$$(x-(2+5i))(x-(2-5i))$$ this one is not as hard as it looks
do you know how to multiply it out easily?

anonymous · Answer

guess we'll never know
