what is the difference between algebraic identify and algebraic equation ?
Answers
Answer:
The difference is that expressions do not include an equal sign and are basically mathematical “phrases.” Equations include an equal sign, and show equivalency between two mathematical expressions. For example, 2x + b is an algebraic expression, but 2x + b = 14 is an algebraic equation.
Answer:
Step-by-step explanation:
Algebraic expression is an expression that contains at least one variable operation , and a constant .
Algebraic identities is an equality relation A=B. Such that A and B contain some variables and A and B produce the same value as each other regardless of what values are substituted for the variable.
An equation is a statement with an equals sign, stating that two expressions are equal in value, for example 2x + 4 = 12
Solving an equation means finding the value or values for which the two expressions are equal. This means equations are not always true. In the example above,2x + 4 = 12 , the only correct solution for x is 4.
An identity is an equation which is always true, no matter what values are substituted. 2x + 5x = 7x is an identity because 2x + 5x will always equal 7x regardless of the value of x. Identities can be written with the sign ≡, so the example could be written as 2x + 5x = 7x.
