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.

There are four **steps** in **solving** **quadratic** **equations** by this method: **Step** 1: Isolate the and terms. Use the addition and subtraction and isolate the and terms on the left-hand side of the **equation**. Then, use the multiplication and division axioms to eliminate the coefficient from the term.

Steps on How to Derive the Quadratic Formula Then simplify it further. Add the output of step #5 to both sides of the equation. Simplify the right side of the equation. Be careful when you add fractions with different denominators. Express the trinomial on the left side of the equation as the square of a binomial. Simplify and we are done! ...

A **quadratic** **equation** is any **equation** that can be **written** in a form like this: ax2 + bx + c = 0. In this **equation**, a, b, and c are constant numbers. The numbers a and b are called coefficients, becaused they are multiplied with x. X is a variable.
