How to use this tool?
This calculator simplifies, adds, subtracts, multiplies, and divides rational expressions (fractions with polynomials). Enter expressions using standard algebraic notation with x as the variable.
- Enter Expression 1 (required): Type the first rational expression, e.g.,
(x^2-1)/(x-1). Use parentheses for clarity. - Enter Expression 2 (optional): For operations other than Simplify, enter the second expression, e.g.,
(x+1)/(x-2). - Select an Operation: Choose one:
- Simplify – Reduces a single expression to lowest terms.
- Add, Subtract, Multiply, or Divide – Performs the operation on two expressions.
- Click "Calculate" – The result appears below with a brief step description.
Input Format: Use ^ for exponents (e.g., x^2). Separate numerator and denominator with a single slash /. Example: (2x+3)/(x-5). For a single polynomial, just type it (e.g., x^2+1).
Note: The calculator handles polynomials with integer coefficients. If an error occurs, check your syntax (e.g., missing parentheses or extra slashes).
