Answer: option 3. 24m

Explanation:

concept to know: (a+b)²=a²+2ab+b²

(a-b)²=a²-2ab+b²

(2m+3)²-(2m-3)²

=(4m²+12m+9)-(4m²-12m+9) ⇔ Use the formula mentioned above

=4m²+12m+9-4m²+12m-9 ⇔ take off parentheses

=4m²-4m²+12m+12m+9-9 ⇔ move the like term together

=24m ⇔ combine like term

Hope this helps!! :)
