Answer:
2x² - 7x - 39 = 0
=> 2x² - 13x + 6x - 39 = 0
=> x (2x - 13) + 3 (2x - 13) = 0
=> (x + 3)(2x - 13) = 0
=> x + 3 = 0 , x = - 3
=> 2x - 13 = 0, x = 13/2 => 6.5

Answer:
(2x + 13)(x - 3)
Step-by-step explanation:
2x² - 7x -39
-7x = -6x + 13x
=2x² - 6x +13x -39
factorising = 2x(x-3) + 3x -39
= 2x(x-3) + 13(x-3)
= (2x + 13)(x - 3)
