Question

Which of the following is a factor of 2x*4 + 22x*3 + 60x*2? a. 2x*3 b. x*4 c. x+4 d. x+5

Answer 1

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!

Answer 2

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.
