please explain briefly​

Answer 1

Answer:

First take 2 as common in both

2{49a-49b-25a-25b}

2{24a-74b}

48a-148b

Answer 2

Answer:

24(a-b)²

Step-by-step explanation:

49(a-b)² - 25(a+b)² = 49(a²-2ab+b²) - 25(a²+2ab+b²)

= 49a² - 98ab + 49b² - 25a² + 50ab - 25b²

= 24a² - 48ab + 24b²

= 24(a² - 2ab + b²)

= 24(a-b)²

Hope it helps you:)
