Question

Please someone tell the three algebraic identities​

Answer 1

Answer:

What are the three algebraic identities in Maths?

Identity 1: (a+b)^2 = a^2 + b^2 + 2ab.

Identity 2: (a-b)^2 = a^2 + b^2 – 2ab.

Identity 3: a^2 – b^2 = (a+b) (a-b)

Answer 2

Answer:

(a+b)²=a²+b²+2ab

(a-b)²=a²+b²-2ab

a²-b²=(a+b)(a-b)

(x+a)(x+b)=x²+(a+b)x+ab
