Question

( a – b) + ( a + b) – ( a + b )( a – b ) =______

Answer 1

Answer:

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

Step-by-step explanation:

a-b+a+b-(a²-b²)

2a-a²-b²

a(2-a)-b²

Answer 2

Answer:

Hey buddy,

The solution is given below,

Using Identity a²-b²= (a+b)(a-b)

→( a – b) + ( a + b) – ( a + b )( a – b )

→ a - b + a + b - (a²-b²)

→2a- a² + b²

.

I hope, I could help with that.
