Doing a factorization of the trinomial, we get:

[tex]2x^2(x^2+11x+30)[/tex]

Which factors into:

[tex]2x^2(x+5)(x+6)[/tex]

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

Hope that helped!

So,

I will assume that you mean:
[tex]2x^4 + 22x^3 + 60x^2[/tex]

Factor.
[tex](2x^2)(x^2 + 11x + 30)[/tex]
[tex](2x^2)(x+6)(x+5)[/tex]

The correct answer is D.
