Which of the following is a factor of 2x4 + 22x3 + 60x2? a. 2x3 b. x*4 c. x+4 d. x+5
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.
