Algebra Inequalities Calculator

Frequently Asked Questions

• What can this algebra inequalities calculator solve?

  

  This free algebra inequalities calculator helps you solve linear, quadratic, polynomial, rational, and compound inequalities with clear, step-by-step explanations.

• Is this algebra inequalities calculator free?

  

  Yes, it’s completely free to use. You can solve inequality problems online and get step-by-step explanations.

• Can I scan a math problem with my camera?

  

  Yes. Use the ScanMath app to scan the problem, and it will generate step-by-step solutions automatically.

• What does “No Solution” mean?

  

  "No solution" indicates that the inequality is true when the variable has no real value. For instance, since x² + 1 is always positive, x² + 1 < 0 has no real solution.

• What does “All Real Numbers” mean?

  

  "All real numbers" indicates that the inequality is satisfied by every real value of the variable. For instance, the solution is (-∞, ∞) since x² + 1 > 0 is always true for real x.

• What is the solution set of an inequality?

  

  The solution set is all values of the variable that make the inequality true. Instead of one number, an inequality can have a range of values, often written in inequality form (like x > 3) or in interval notation (like (3, ∞)).
