Q: What if a is zero?

If a = 0, the inequality becomes b > c or b < c. The result is either all real numbers or no solution.

Q: Can I use decimal coefficients?

Yes, decimal coefficients are fully supported.

Q: Does this support ≥ or ≤?

Not directly. Use > or < and note whether the boundary is included or not.

Q: What about quadratic inequalities?

This calculator only handles linear inequalities. For quadratics, use the Quadratic Equation solver.

Question 1

What happens when a is negative?

Answer

When a < 0, the inequality direction flips when dividing. For example, -2x > 6 becomes x < -3.

Question 2

What if a is zero?

Answer

If a = 0, the inequality becomes b > c or b < c. The result is either all real numbers or no solution.

Question 3

Can I use decimal coefficients?

Answer

Yes, decimal coefficients are fully supported.

Question 4

Does this support ≥ or ≤?

Answer
