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.

**Summary**

- Quadratic Equation in Standard Form: ax 2 + bx + c = 0
- Quadratic Equations can be factored
- Quadratic Formula: x = −b ± √ (b2 − 4ac) 2a
- When the Discriminant ( b2−4ac) is: positive, there are 2 real solutions zero, there is one real solution negative, there are 2 complex solutions

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.

The quadratic formula is a technique that can be used to solve quadratics, but in order to solve a quadratic using the quadratic formula the problem must be in the correct form. To solve a quadratic using the quadratic formula the quadratic must be in the form **ax2 + bx + c = 0**.
