The **Quadratic** **Formula**: For ax2 + bx + c = 0, the values of x which are the solutions of the equation are given by: For the **Quadratic** **Formula** to work, you must have your equation arranged in the form "(**quadratic**) = 0". Also, the "2a" in the denominator of the **Formula** is underneath everything above, not just the square root.

A quadratic equation is an equation that can be written as **ax ² + bx + c** where a ≠ 0 In other words, a quadratic equation must have a squared term as its highest power Examples of quadratic equations.

A quadratic equation is any **polynomial equation of degree 2**, or any equation in the form , or any equation that can be expressed in that form. The quadratic formula is a formula for **solving any quadratic equation** by completing the square on the equation , treating a, b, and c as constants.

Substitute the first pair of values into the general form of the **quadratic** **equation**: f(x) = ax^2 + bx + c. Solve for a. For example, 5 = a(1^2) + b(1) + c simplifies to a = -b - c + 5.
