Answer:

(a - b - 5)(a - b + 5)

Explanation:

(a - b)² = a² + b² - 2ab

Given

a² + b² - 2ab - 25

= (a - b)² - 25 ← this is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

(a - b)² - 25

= (a - b)² - 5²

with a = a - b and b = 5 , so

(a - b)² - 5²

= (a - b - 5)(a - b + 5)
