How do I factor this?

24m⁴n - 12m³n - 12m²n

Factor out 12m²n from the expression:

12m²n(2m² - m - 1)

Write -m as a difference:

12m²n(2m² + m - 2m - 1)

Factor out m from the expression:

12m²n(m(2m + 1) - 2m - 1)

Factor out the negative sign from the expression:

12m²n(m(2m + 1) - (2m + 1))

Factor out 2m + 1 from the expression which gives us the final answer of:

12m²n(2m + 1)(m - 1)

I hope this helped you and if you need me to explain something further or if you have any questions just ask!

(If I did help you I would greatly appreciate a thanks, or if I REALLY helped you a Brainliest would be amazing!)
