Graphing Quadratic Inequalities Calculator
Solve and graph quadratic inequalities with ease using our calculator.
What is the Graphing Quadratic Inequalities Calculator & How does it work?
Quadratic inequalities involve a quadratic expression that is either greater than, less than, greater than or equal to, or less than or equal to zero. These inequalities can be solved by finding the roots of the corresponding quadratic equation and then determining the intervals where the inequality holds true.
The general form of a quadratic inequality is. The roots of the equation ax2 + bx + c = 0 can be found using the quadratic formula: x = (-b ± √(b2 – 4ac)) / (2a).
Once the roots are determined, test points in each interval defined by the roots to determine where the inequality holds true. The solution set will be the union of these intervals.
The general form of a quadratic inequality is
ax^2 + bx + c > 0
a = coefficient of x2, b = coefficient of x, c = constant term
Once the roots are determined, test points in each interval defined by the roots to determine where the inequality holds true. The solution set will be the union of these intervals.

Frequently Asked Questions
How do I use the Graphing Quadratic Inequalities Calculator?
Enter your quadratic inequality in the form ax^2 + bx + c > 0, then click ‘Solve’ to find the solution intervals.
What is a quadratic inequality?
A quadratic inequality involves a quadratic expression that is either greater than, less than, greater than or equal to, or less than or equal to zero.
How do I solve a quadratic inequality manually?
First, find the roots of the corresponding quadratic equation. Then, test intervals around these roots to determine where the inequality holds true.
Can this calculator handle inequalities with fractions?
Yes, you can input quadratic inequalities with fractional coefficients, and the calculator will solve them accordingly.
What does the graph show in a quadratic inequality?
The graph shows the parabola of the quadratic equation and highlights the intervals where the inequality is satisfied.
How do I interpret the solution intervals provided by the calculator?
The intervals indicate where the quadratic expression satisfies the inequality. For example, if the solution is x < -2 or x > 3, these are the ranges where the inequality holds true.
Can this calculator also graph the equality part of the quadratic equation?
Yes, the calculator will graph both the inequality and the corresponding equality (ax^2 + bx + c = 0) to provide a visual representation of the solution.
