Question

simplify (a+b) (a-b) - (a+b) (a+b) - (a^2-b^2+2ab)

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer: -( (a+b)²+2ab)

Step-by-step explanation:

(A+b)(a-b) = a²-b²

(A+b)(A+b) = (A+b)²= a²+b²+2ab

So,

A²-b²-(a+b)²-(a²-b²+2ab)

= A²-b²-a²-b²-2ab-a²+b²-2ab

=-a²-b²-4ab

-(a²+b²+2ab+2ab)

-( (a+b)²+2ab)
