How to Use the Solve The Inequality Calculator
- Enter your inequality in the input field. Use standard mathematical notation with variable
x. Examples:2x+3>7,x^2-4<0,3x-5>=1. - Click the "Solve" button to compute the solution.
- View the result displayed as the solution set (e.g.,
x > 2or1 < x < 3). - Review the steps shown below the solution, including the standard form, roots, and reasoning about inequality direction.
Supported inequalities: Linear (e.g., ax+b > c) and quadratic (e.g., ax^2+bx+c < 0) with operators >, <, >=, <=, or =. Use ^ for exponents (e.g., x^2).
Note: Only variable x is supported. Ensure the inequality is entered in a single line without spaces around operators for best parsing.

Frequently Asked Questions
This calculator solves linear inequalities (e.g., 2x+3>7) and quadratic inequalities (e.g., x^2-4<0). It supports operators >, <, >=, <=, and =.
Enter the inequality in standard mathematical notation. Use 'x' as the variable, '^' for exponentiation (e.g., x^2), and standard operators. Examples: 2x+3>7, x^2-4<0, 3x-5>=2x+1.
Yes, after solving, the calculator displays a step-by-step breakdown of the solution, including converting to standard form, finding roots, and determining the solution set based on the inequality sign.
