Answer:

$x^4+x^2-12$

Step-by-step explanation:

We'll write the polynomial using only the roots required to simplify calculations. However, it states the final answer should not have a radical or complex number in. Therefore, we need to rid them:

$(x+\sqrt{3})(x-\sqrt{3})(x-2i)(x+2i)$

Expanding this, we get:

$(x^2-3)(x^2+4),\\\fbox{$x^4+x^2-12$}$ .
