Question

algebraic identities​

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

Answer:

1.(a+b)²= a²+ b²+2ab

2.(a-b)²= a²-2ab +b²

3.(a+b)(a-b)= a²-b²

4.( a+b+c) = a+b+c+2ab+2ba+2ca

5.(x+a) (x+b) = x²+ax+bx+ab
