Quadratic FormulaWhen in doubt, use the quadratic formula! This formula allows us to solve any type of quadratic equation. If the equation can be factored, factoring is usually the quicker method. However, not all equations can be factored easily. In this case, the quadratic formula always works. It just takes a little more time due to the heavy computation. But... it's not hard! The Quadratic Formula
Once you substitute the values for a, b, and c, you'll just need to use some basic math to arrive at the solution. It's really pretty easy. Take a look! Example 1
Let's take a look at one more example. We'll look at a real world application using quadratic equations. Example 2
