Polynomial inequalities appear frequently in algebra, calculus, and applied mathematics. Understanding their solutions is crucial for students, engineers, and anyone working with mathematical models. The Polynomial Inequality Calculator is an intuitive tool designed to solve linear, quadratic, and cubic inequalities efficiently, providing roots, solution sets, and interval notations.

Whether you are tackling homework problems, preparing for exams, or analyzing functions, this tool saves time and ensures accuracy.

What is a Polynomial Inequality Calculator?

A polynomial inequality is an expression like axn+bxn−1+...+k>cax^n + bx^{n-1} + … + k > caxn+bxn−1+…+k>c, where the polynomial is compared to a value using inequality signs (>, ≥, <, ≤).

The Polynomial Inequality Calculator:

  • Finds real roots/zeros of the polynomial.
  • Determines the solution set for the inequality.
  • Provides interval notation for the solutions.
  • Analyzes end behavior, vertex (for quadratics), and y-intercept.

This helps visualize where the polynomial satisfies the inequality.

How to Use the Polynomial Inequality Calculator

  1. Select Polynomial Degree: Linear (ax + b), Quadratic (ax² + bx + c), or Cubic (ax³ + bx² + cx + d).
  2. Enter Coefficients: Input a, b, c, and d (for cubic). The leading coefficient cannot be zero.
  3. Choose Inequality Type: Greater than (>), Greater than or equal (≥), Less than (<), or Less than or equal (≤).
  4. Set Right-Side Value: Default is 0, but you can enter any number.
  5. Click Calculate: The calculator displays polynomial expression, roots, solution set, interval notation, and analysis.
  6. Reset: Clear all inputs using the Reset button to solve a new inequality.

Example: Solving a Quadratic Inequality

Suppose we have the quadratic inequality:2x2−3x−5>02x^2 – 3x – 5 > 02×2−3x−5>0

  • Polynomial Degree: Quadratic
  • Coefficients: a = 2, b = -3, c = -5
  • Inequality Type: Greater Than (>)

Results from the calculator:

  • Polynomial Expression: 2x² – 3x – 5
  • Roots: x ≈ -1.000, 2.500
  • Solution Set: x < -1.000 or x > 2.500
  • Interval Notation: (-∞, -1.000) ∪ (2.500, ∞)
  • Vertex: (0.750, -6.125)
  • Y-Intercept: -5
  • End Behavior: U-shaped (opens up)

This shows clearly where the inequality holds.
