Answer 1

Answer:

(6y -7)(6y + 7)  is the answer

Step-by-step explanation:

36y² - 49

(6y)² - (7)²

a² - b² = (a + b )(a - b)

= (6y -7)(6y + 7)

Answer 2

Step-by-step explanation:

36^2 - 49

(6y)^2 - (7)^2

BY ID 3 : (a)^2 - (b)^2 = (a + b ) (a -b )

Here a = 6y ; b = 7

(6y + 7) ( 6y - 7 )    Ans
