If [tex]x_0[/tex] is a zero of a polynomial, then the polynomial is a multiple of [tex](x-x_0)[/tex]
So, our polynomial is a multiple of
[tex](x+4)(x-4)(x-6)=x^3-6x^2-16x+96[/tex]
The answer isn't unique in theory, since every multiple of this polynomial would be fine. I don't know what the website expects as an answer honestly.
