Doing a factorization of the trinomial, we get:

\(2x^2(x^2+11x+30)\)

Which factors into:

\(2x^2(x+5)(x+6)\)

Therefore x+6 is a factor of the trinomial, and (d) is your answer.

Hope that helped!

So,

I will assume that you mean:
\(2x^4 + 22x^3 + 60x^2\)

Factor.
\((2x^2)(x^2 + 11x + 30)\)
\((2x^2)(x+6)(x+5)\)

The correct answer is D.
