Question

Can anyone know that all algebraic identities?

Answer 1

Answer:

Algebraic identities are algebraic equations which are always true for every value of variables in them. ... In an algebraic identity, the left-side of the equation is equal to the right-side of the equation. For example, (a+b)2 = a2+2ab+b2 , which is true for all the values of and b.

Answer 2

Step-by-step explanation:

$1)(x + y) {}^{2} = x {}^{2} + 2xy + {y}^{2} \\ 2)(x - y) {}^{2} = {x}^{2} - 2xy + y {}^{2} \\ 3) {x}^{2} - {y}^{2} = (x + y)(x - y) \\ 4)(x + a)(x + b) = {x}^{2} + \\ (a + b)x + ab$

$5)(x + y + z) {}^{2} = {x}^{2} + {y}^{2} \\ + z {}^{2} + 2xy + 2yz + 2zx \\ 6)(x + y) {}^{3} = {x}^{3} + y {}^{3} + 3 {x}^{2} y \\ + 3x {y}^{2}$
