📌 What is a Cubic Equation?

A cubic equation is a polynomial equation of degree 3. It has the general form:

ax³ + bx² + cx + d = 0, where a ≠ 0.

It can have up to **three real roots** or a combination of real and complex roots.

📌 Applications of Cubic Equations

  • Physics: Used in motion and energy calculations.
  • Engineering: Essential in mechanical and civil engineering designs.
  • Economics: Helps model profit functions and market trends.
  • Data Science: Applied in machine learning and statistical models.
  • Structural Analysis: Used in designing bridges and skyscrapers.

📌 Example Calculations

EquationSolution
2x³ – 4x² – 22x + 24 = 0✅ Roots: x = 4, x = -3, x = 1
x³ – 6x² + 11x – 6 = 0✅ Roots: x = 1, x = 2, x = 3

❓ FAQs

Q1: How many real roots can a cubic equation have?
✅ A cubic equation can have **one, two, or three real roots**.

Q2: Can cubic equations have complex solutions?
✅ Yes! If a cubic equation has only one real root, the other two are complex conjugates.

Q3: What happens if a = 0?
✅ If **a = 0**, the equation becomes quadratic, and the cubic solver won’t work.

Q4: What is the discriminant in a cubic equation?
✅ The discriminant determines the number of real and complex roots.

Q5: Where are cubic equations used?
✅ They are used in engineering, physics, and economics.
