(3x+4) (2x-5)
Step-by-step explanation:
You have 6x^2 - 7x-20, you add and take 8x so now you have
6x^2 - 7x + 8x - 8x - 20 now you take 6x^2 and the + 8x and factorize
6x^2 + 8x = 2x (3x + 4)
and you have - 7x - 8x-20 = - 15x - 20 factorize
-5 (3x + 4) add all up.
2x (3x + 4) - 5 (3x + 4) and you have
(3x+4) (2x-5)
