Question

(a+ b) (a-b) - a²+ b²​

Answer 1

Answer:

0

Step by step explanation:

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

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

a^2 - b^2 - a^2 + b^2

Answer 2

Answer:

SO CONCEPT BASED ON ALGEBRAIC IDENTITIES AND ADDITION AND SUBTARACTION OF ALGEBRAIC EXPRESSIONS.

Step-by-step explanation:

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

= (a^2 - b^2) - (a^2 + b^2) [BY IDENTITY (a+b)(a-b) = a^2 - b^2]

= (a^2 - b^2) - a^2 + b^2

SO YOUR ANSWER IS 0.
