Find values that make a rational expression undefined
Example: (x+5)/(x^2-9), 1/(x-3) + 2/(x+4), or (2x+1)/(x^2-4x+4)
Please enter a valid rational expression. Example: (x+1)/(x-2)
Solution Steps
What are Rational Equations
A rational equation is an equation containing one or more rational expressions. These are fractions where both the numerator and denominator are polynomials. Solving these equations requires finding values that satisfy the equation while excluding values that make denominators zero (restricted values).
Our advanced calculator provides unique solutions for each equation you enter, with detailed step-by-step explanations. Unlike basic calculators, we generate different solving paths based on your specific equation, ensuring you understand the entire process.

How It Works
Our calculator uses sophisticated algorithms to analyze your rational equations and generate unique solutions every time:
Equation Analysis: Parses your input to identify the structure of rational expressions.
Pattern Recognition: Detects specific patterns in your equation to determine the optimal solving approach.
Restricted Values: Computes values that make denominators zero by solving denominator equations.
Solution Generation: Creates a unique solution path based on equation complexity and structure.
Step Customization: Tailors the explanation steps to your specific equation for better understanding.

Why Our Solutions Are Unique
Unlike basic calculators that provide generic solutions, our algorithm analyzes each equation to create a tailored solving path. For example:
Equations with quadratic denominators get factoring steps
Expressions with multiple terms get LCD identification
Complex fractions receive simplification steps
Each solution includes verification against restricted values
Frequently Asked Questions
What makes this calculator different?
Unlike standard calculators that provide the same generic steps for every equation, our calculator analyzes your specific equation to generate a unique solution path. We provide tailored steps based on the complexity and structure of your input.
Why do I get different solutions for similar equations?
Our calculator recognizes subtle differences in equations (like quadratic denominators, multiple terms, or complex fractions) and adjusts the solving approach accordingly. This ensures you get the most appropriate method for your specific equation.
How accurate are the solutions?
Solutions are generated using algebraic algorithms that follow standard mathematical principles. We verify all solutions against restricted values and check for extraneous solutions to ensure accuracy.
Can I solve equations with complex denominators?
Absolutely! Our calculator handles equations with quadratic denominators, multiple rational expressions, and complex fractions. The solution steps will adapt to show factoring, LCD identification, and simplification as needed.
How does the calculator handle restricted values?
Before solving, we identify all values that would make any denominator zero. These restricted values are displayed first, and any solution matching these values is automatically eliminated as invalid.
Can I see different solving methods?
Yes! Try entering the same equation with different structures (e.g., "1/(x+2) + 3/(x-1) = 5" vs. "(1/(x+2)) + (3/(x-1)) = 5"). You'll see different solving approaches based on how the equation is formatted.
