Explanation & Answer

Thank you for the opportunity to help you with your question!

9m^2-(m-2)^2

(3m)^2 - (m-2)^2                           Hint: write 9 = 3^2

(3m+m-2) (3m-(m-2))                   Hint: use formula a^2 - b^2 = (a+b)(a-b)

(4m-2) (3m-m+2)

(4m-2) (2m+2)

Hence the factors are (4m-2) (2m+2)

Please let me know if you need any clarification. I'm always happy to answer your questions. Kindly best this answer if it has helped you.
