What is the completely factored form of 6x2 – 13x-5?
(2x - 5)(3x + 1)
(2x + 5)(3x - 1)
(2x - 1)(3x - 5)
(2x + 1)(3x + 5)

(3x + 1) (2x - 5) or (2x - 5)(3x + 1), that's option A

Step-by-step explanation:

6x² - 13x - 5

To factorize look for two numbers that their sum will give -13 and their product will give = 6 x -5 = -30

The numbers are: -15 and 2

= 6x² - 15x + 2x - 5

= 3x(2x - 5) +1(2x - 5)

= (3x + 1) (2x - 5)

Option A is the answer.
