Root Calculator Formula

The Root Calculator uses mathematical formulas to find the roots of equations. The specific formula depends on the type of equation you're solving. Here are some common formulas:

Linear Equation (ax + b = 0)

The root of a linear equation is given by: x = -b/a

Quadratic Equation (ax² + bx + c = 0)

The roots of a quadratic equation are given by: x = [-b ± √(b² - 4ac)] / (2a)

Cubic Equation (ax³ + bx² + cx + d = 0)

The roots of a cubic equation can be found using the cubic formula, which involves solving a depressed cubic equation and using trigonometric functions.

For higher-order equations, numerical methods such as the Newton-Raphson method or iterative techniques are often used to approximate the roots.

Example Calculations

Let's look at some examples to see how the Root Calculator works in practice.

Example 1: Linear Equation

Find the root of the equation 2x + 3 = 0.

Using the linear equation formula: x = -b/a = -3/2 = -1.5

The root of the equation is x = -1.5.

Example 2: Quadratic Equation

Find the roots of the equation x² - 5x + 6 = 0.

Using the quadratic formula: x = [5 ± √(25 - 24)] / 2 = [5 ± 1] / 2

The roots of the equation are x = 3 and x = 2.

Example 3: Cubic Equation

Find the roots of the equation x³ - 6x² + 11x - 6 = 0.

Using the cubic formula or numerical methods, the roots of the equation are x = 1, x = 2, and x = 3.
