Answer:

hope it will help you....

Answer 2

Step-by-step explanation:

36a²-(x-y)²

as 36 is square of 6

and a² is sqaure of a

so 36a² will be square of 6a

so 36a²=(6a)²

so above question can be written as

(6a)²-(x-y)²

as we know the identity that

a²-b²=(a-b)(a+b)

so it will be

[6a-(x-y)] [6a+(x-y)]

or,

(6a-x+y)(6a+x-y)
