Applications of Quadratic Equations

 There are different methods to solve QuadraticEquations.  

1. Graphing: zeros can be found where the quadratic equation crosses the x-axis {x-intercepts).

2. Factoring: use the steps for factoring to break down a quadratic expression into factors.

3. Quadratic Formula: use the formula to find the roots of a quadratic equation.

The most common use of the quadratic equation in real world situations is in the aiming of missiles and other artillery by military forces. Parabolas are also used in business, engineering and physics. Engineers use the quadratic equation along with other advanced types of math when making their designs. Automotive, chemical, electrical and even audio engineers all use this method. In business when product developers create a new item to sell, they use the quadratic formula to create a demand curve and use it to determine the optimal price to sell the units to maximize profits.
