Question

Which of the following is a factor of the trinomial:x^2 - 6x - 16A) x+8B) x-8C) x-4D) x-2E) x+4

Answer 1

You have the following polynomial:

x² - 6x - 16

the factorized previous expression can be found as follow:

(x - )(x + )

remind that the first number is the subtraction of two numbers and the second number is the multiplication of the same both numbers. In this case, you have:

(x - 8)(x + 2)

Hence, one of the factors is x - 8
