What is Cubic Equation?
A cubic equation is a polynomial equation of the form:
ax^3 + bx^2 + cx + d = 0
where:
- “a,” “b,” “c,” and “d” are coefficients, and “a” is not equal to 0.
- “x” represents the variable you’re solving for.
- The equation has a degree of 3, which means it’s a cubic equation.
All Formulae Related to Cubic Equation
- Vieta’s Formulas for the Sum and Product of Roots:
- For a cubic equation ax^3 + bx^2 + cx + d = 0:
- Sum of the roots (x1, x2, and x3): x1 + x2 + x3 = -b/a
- Product of the roots (x1, x2, and x3): x1 * x2 * x3 = -d/a
- For a cubic equation ax^3 + bx^2 + cx + d = 0:
- Cardano’s Formula for Solving the General Cubic Equation:
- The general cubic equation ax^3 + bx^2 + cx + d = 0 can be solved using Cardano’s formula. However, the formula is quite lengthy and involves complex calculations.
- Depressed Cubic Equation:
- In some cases, you can transform a cubic equation into a “depressed cubic” by substituting x = y – (b/3a). The depressed cubic is of the form y^3 + py + q = 0, where p and q are known values. Solving the depressed cubic is simpler than solving the general cubic.
- Special Cases:
- If the cubic equation has specific patterns or symmetries, you may be able to find the roots through simplifications or trigonometric methods. These cases are encountered in advanced mathematics and require specific knowledge of the problem’s context.
- Numerical Methods:
- For practical purposes, cubic equations are solved using numerical methods like the Newton-Raphson method or by utilizing specialized software or calculators.
