What is an Equivalent Expression?

In mathematics, two expressions are equivalent if they simplify to the same value, no matter what variable values are substituted. For instance:

  • Expression 1: 2(x+3)2(x + 3)2(x+3)
  • Expression 2: 2x+62x + 62x+6

After simplification, both expressions represent the same value for any xxx. Hence, they are equivalent.


How to Use the Equivalent Expressions Calculator

Using this tool is simple and straightforward:

  1. Enter Expressions
    • Input your first expression in the “Expression 1” field.
    • Input the second expression in the “Expression 2” field.
  2. Click “Calculate”
    • The calculator instantly simplifies both expressions and compares them.
  3. View Results
    • If the expressions are equivalent, a message will confirm it.
    • If they are not, the tool will notify you that the expressions are different.
  4. Reset the Calculator
    • Use the “Reset” button to clear the fields and enter new expressions.

This simple interface ensures you can focus on math, not formatting or manual calculations.

    Result: The expressions are equivalent.

Example 2:

  • Expression 1: x2+2x+1x^2 + 2x + 1×2+2x+1
  • Expression 2: (x+1)2(x + 1)^2(x+1)2
    Result: The expressions are equivalent.

Example 3:

  • Expression 1: 5x+75x + 75x+7
  • Expression 2: 5(x+7)5(x + 7)5(x+7)
    Result: The expressions are not equivalent.

These examples demonstrate how the calculator handles both simple and more complex algebraic expressions.
