HELP!!!!!!!
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

anonymous · Answer

k this is not as bad as it looks

anonymous · Answer

first you know if $2+3i$ is a zero then so is its conjugate $2-3i$ so you actually have 4 zeros

anonymous · Answer

second you know in factored form it looks like 
$$(x-4)(x+8)(x-(2+3i))(x-(2-3i))$$

anonymous · Answer

third $(x-4)(x+8)$ is elementary algebra, the real hard part is 
$$(x-(2+3i))(x-(2-3i))$$ but i can show you a snap way to compute that, actually two ways if you like

anonymous · Answer

unless you already know how
