Answer:

(x + 4) × (2x - 5)

Step-by-step explanation:

Begin by writing 3x as a difference
2x^2 + 8x - 5x - 20

Factor out 2x from the expression
2x × (x + 4) - 5x - 20

Factor out -5 from the expression
2x × (x + 4) - 5 (x + 4)

Factor out x + 4 from the expression
(x + 4) × (2x - 5)

Hope this helps!!
