Which of the binomials below is a factor of this trinomial? - 3x^2-21x+24 x-4 x+1 x+4 x-1

-3x^2-21x+24

Step-by-step explanation:

Kindly separate the answer choices: (x - 4), (x + 1), (x + 4), (x - 1). The trinomial is thus - 3x^2-21x+24, which can be factored as follows: - 3 (x^2 + 7x - 8)

Then we have - 3x^2-21x+24 = - 3 (x^2 + 7x - 8), which factors further into:

-3 (x + 8) (x - 1) and so we conclude that the only binomial that is a factor of

-3x^2-21x+24 is (x - 1).
