Question

:) Expand the following:
1. (a+b)²
2. a²-b²​

Answer 1

Answer:

1. (a+b)²

Answer =  (a +b)2 = a2 + 2ab + b2. 2. (a - b)2 = a2 - 2ab + b2

2. a²-b²​

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

Answer 2

Step-by-step explanation:

These are the algebraic identities

1. (a+b)² on expanding is a²+2ab+b²

2. a²-b² on expanding is (a+b)(a-b)
