Step-by-step explanation:

1. a²- b²

2. x²-(a-b)x-ab

Explanation of no. 2

(x-a)(x+b)

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

= x²-bx+ax-ab

We can stop here, or continue by taking ‘x’ as common in the middle term. So, we get

= x²-(a-b)x-ab

Therefore, it is in the form of ax²-bx-c.

Therefore, the expansion form of (x-a)(x+b) is

x²-(a-b)x-ab.
