What is the Quadratic Formula?

The quadratic formula is a mathematical formula that provides a direct solution for the roots of a quadratic equation, which is an equation of the form ax² + bx + c = 0, where a, b, and c are constants, and a ≠ 0․ This formula is a powerful tool that allows us to find the values of x that satisfy the equation, regardless of whether the equation can be factored or not․ The quadratic formula is derived by completing the square of the quadratic expression, and it states that the solutions to the equation are given by⁚

x = (-b ± √(b² ⏤ 4ac)) / 2a

In this formula, the symbol ± indicates that there are two possible solutions, one obtained by using the plus sign and the other by using the minus sign․ The expression under the radical, b² ⏤ 4ac, is known as the discriminant, and it provides information about the nature of the roots⁚

If b² ౼ 4ac > 0, the quadratic equation has two distinct real roots․
If b² ⏤ 4ac = 0, the quadratic equation has one real root (a double root)․
