## Interesting Facts

• The Quadratic Formula is also known as the "Quadratic Equation Formula" or "Completing the Square".
• The formula is attributed to the ancient Babylonians, who used it to solve complex algebraic problems.
• The Quadratic Formula can be derived from the process of "completing the square", which involves adding a constant term to a quadratic expression to create a perfect square trinomial.

## The Formula

x = (-b ± √(b2 - 4ac)) / 2a

Where x is the variable being solved for, and a, b, and c are the coefficients of the quadratic equation. The ± sign indicates that there are two solutions to the equation, one with a plus sign and one with a minus sign.

## Example

Let's say you have a quadratic equation: 2x2 + 5x - 3 = 0

To solve for x using the Quadratic Formula, first identify the values of a, b, and c:

• a = 2
• b = 5
• c = -3

Then plug these values into the Quadratic Formula:

x = (-5 ± √(52 - 4(2)(-3))) / 2(2)

Simplifying the formula gives two solutions:

• x = (-5 + √49) / 4 = 1/2 or -3
• x = (-5 - √49) / 4 = -3 or 1/2

Therefore, the solutions to the quadratic equation 2x2 + 5x - 3 = 0 are x = 1/2 and x = -3.

## Real-Life Applications

The Quadratic Formula has many real-life applications, such as:

• Calculating projectile motion in physics
