Question

algebraic identity ??? ​

Answer 1

Answer:

An algebraic identity is an equality that holds for any values of its variables. For example, the identity ( x + y ) 2 = x 2 + 2 x y + y 2 (x+y)^2 = x^2 + 2xy + y^2 (x+y)2=x2+2xy+y2 holds for all values of x and y.

Answer 2

Identity I (a+b)2 = a2+2ab+b2Identity II (a-b)2 = a2- 2ab+b2Identity III a2-b2= (a+b) (a-b)Identity IV (x+a) (x+b) = x2+(a+b) x+ab
