Ok, I have no idea how to do this, or really what even its asking. The original question wasn't in English, so I apologize if the vernacular is off.

We have a polynomial $P(X) = X^4 - 3X^2 - 4$ (of $\mathbb R[X]$). I need to write $P(X)$ as a product of two polynomials of degree 1 and a polynomial of degree 2 with a negative discriminant.

It also gives me a hint: To search for the roots, we can use $Z = X^2$ for the time being.

I wish I could say more, and give you the way that I *attempted* solved this, but I legitimately have no idea what to do here. Any help is appreciated, thanks.
