You can put this solution on YOUR website! Find a polynomial P(x) with real coefficients having a degree 4, leading coefficient 4, and zeros 3-i, and 3i.
---
If the coefficients are Real 3+i and -3i must also be zeros.
-------------------------
f(x) = (x-4)(x+3i)(x-3i)(x-(3+i))(x-(3-i)
-----
f(x) = (x-4)(x^2+9)((x-3)^2+1)
--------
etc.
