Question

Factorise completely
(a - b)² -x²​

Answer 1

Answer:

( a - b + x ) ( a - b - x )

Step-by-step explanation:

( a - b )² - x²

= ( a - b + x ) ( a - b - x )

Answer 2

Answer:

(a-b-x)(a-b+x)

Step-by-step explanation:

(a-b)²-x²

property = a²-b²

=(a-b)(a+b)

here a = (a-b)

and b = x

so,

(a-b)²-x² = (a-b-x)(a-b+x)
