Question

Which of the following is a factor of the polynomial 6x^2-x-15

Answer 1

6x² - x - 15

Rewrite the expression by writing -x as a difference:

6x² + 9x - 10x - 15

Factor out 3x from the expression:

3x * (2x + 3) - 10x - 15

Factor out -5 from the expression:

3x * (2x + 3) - 5 * (2x + 3)

Factor out the expression:

(2x + 3) * (3x - 5)



Therefore the answer to your question would be:

D) 3x - 5
