ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions.

Answer:
(4x - 2).
Step-by-step explanation:
12x^2 + 20x - 6x - 10
= 12x^2 + 14x - 10
= 2(6x^2 + 7x - 5)
= 2(2x - 1)(3x + 5)
= (4x - 2)(3x + 5)
= 12x^2 + 20x - 6x - 10
Hope this helps!
