Answer:

(5m-9n) (5m+9n)

Step-by-step explanation:

25m^2−81n^2

Rewriting each term

(5m)^2 - (9n)^2

This is the difference of squares

a^2 - b^2 = ( (a-b) (a+b)

(5m-9n) (5m+9n)

Answer:

(5m + 9n)(5m - 9n)

Step-by-step explanation:

we know a² - b² = (a + b)(a - b)

=>  Similarly, 25m² - 81n²

=> (5m + 9n)(5m - 9n)
