2x²-12x-80
First factor out 2 from each term to make it easier to handle.
2(x²-6x-40)
What two number that are 6 apart (since the 6 is negative) multiply to make 40?
10 and 4 work.
Since the 6 is negative, put the negative with the higher number, and you're done.
2(x-10)(x+4) ◄
Check it
2 (x² - 10x + 4x - 40)
2 (x² - 6x - 40)
2x² - 12x - 80 ■
