An identity equation is an equation that is always true for any value substituted into the variable For example 2 x 1 2x 2 2 x 1 2x 2 is an identity equation One way of checking is by simplifying the equation begin aligned 2 x 1 2x 2 2x 2 2x 2 2 2 end aligned 2 x 1 2x 2 2 2x 2 2x 2 2 Identity equations are equations that are true no matter what value is plugged in for the variable. If you simplify an identity equation, you'll ALWAYS get a true statement. Learn about identity equations in this tutorial, and then create your own identity equation.

What Is An Identity Equation In AlgebraAn identity is an equation that is true for all values of the variables. For example: ( x. +. y. ) 2. = x. 2. +. 2. x. y. +. y. 2. The above equation is true for all possible values of x and y, so it is called an identity. Strictly speaking we should use the "three bar" sign to show it is an identity as shown below. Some Standard Algebraic Identities list are given below Identity I a b 2 a 2 2ab b 2 Identity II a b 2 a 2 2ab b 2 Identity III a 2 b 2 a b a b Identity IV x a x b x 2 a b x ab Identity V a b
