How to use the Polynomial Calculator?

Step by step:

  • Choose one of the options: Find Roots (Quadratic), Find Roots (Cubic), Find Derivative, Add Polynomials, or Multiply Polynomials.
  • Enter the information that is asked for in the chosen formula. “(Coefficients (highest to lowest degree), X value for evaluation, First Polynomial Coefficients, and Second Polynomial Coefficients”.
  • Click Calculate and view the result in seconds.

Example 1: Choose to calculate the "Evaluate Polynomial” operation.

Evaluate the polynomial p(x) = 2x² − 3x + 1 at x = 4.
Input:
Coefficients (highest to lowest degree): 2, -3, 1
X value for evaluation: 4

Step by step:

  • Polynomial Evaluation
  • Coefficients (highest to lowest degree): 2, -3, 1
  • Evaluating at x = 4
  • Term 0: 2 × 4² = 32
  • Term 1: -3 × 4¹ = -12
  • Term 2: 1 × 4⁰ = 1
  • Polynomial: P(x) = 2x² - 3x + 1
  • P(4) = 21

result:

  • Polynomial: 2x² - 3x + 1
  • Value: 21
  • Degree: 2

Example 2: Choose to calculate the "Quadratic” operation.

Find Roots (Quadratic) of 2x² − 3x + 1 = 0.
Input:
Coefficients (highest to lowest degree): 2, -3, 1. Enter 0 in all other boxes.

Step by step:

  • Quadratic Root Finding
  • Polynomial: 2x² - 3x + 1 = 0
  • Discriminant: Δ = b² - 4ac = (-3)² - 4(2)(1) = 1
  • Discriminant > 0: Two distinct real roots
  • Root 1: 1
  • Root 2: 0.5

result:

  • Root1: 1
  • Root2: 0.5
  • Discriminant: 1

Example 3: Choose to calculate the "Cubic” operation.

Find Roots (Cubic) x³ − 6x² + 11x − 6 = 0.
Input:
Coefficients (highest to lowest degree): 1, -6, 11, -6, enter 0 in all other boxes.

Step by step:

  • Cubic: 1x³ - 6x² + 11x - 6 = 0
  • Root found: 3
  • Root found: 1
  • Root found: 2

result:

  • Root 1: 3
  • Root 2: 1
  • Root 3: 2

Example 4: Choose to calculate the "Derivative” operation.

Find Derivative Polynomial: f(x) = 3x³ − 4x + 7.
Coefficients (highest to lowest degree): 3, 0, -4, 7

Step by step:

  • Original polynomial degree: 3
  • Term 3x³ → 9x²
  • Term 0x² → 0x¹
  • Term -4x¹ → -4x⁰

result:

  • Derivative coeffs: 9, 0, -4

Example 5: Choose to calculate the "Add Polynomials” operation.

Polynomials: (2x² − 3x + 4) and (x² + 5x − 2)
Input:
First Polynomial Coefficients: 2, -3, 4
Second Polynomial Coefficients: 1, 5, -2

Step by step:

  • 2 + 1 = 3
  • -3 + 5 = 2
  • 4 + -2 = 2

result:

  • Sum coeffs: 3, 2, 2

Example 6: Choose to calculate the "Multiply Polynomials” operation.

Polynomials: (x + 2) and (x − 3)
Input:
First Polynomial Coefficients: 1, 2
Second Polynomial Coefficients: 1, -3

Step by step:

  • 1 × 1 added to position 0
  • 1 × -3 added to position 1
  • 2 × 1 added to position 1
  • 2 × -3 added to position 2

result:

  • Product coeffs: 1, -1, -6
