since complex roots come in conjugate pairs, the polynomial has to also have 2i as one of the roots... so the polynomial having 11, 2i, 2i as roots has to be at least a third degree polynomial

so, it would be (x  11) (x  2i) (x  (2i)) ?

\[(x^3 11x^2 2ix^2 +2ix^2 + 22i 22i 4i^2)\] that's the unsimplified answer, so the simplified one is \[(x^3  11x^2 4i^2)\] right?
