There are a wide variety of jobs that use the quadratic equation. **Actuaries, mathematicians, statisticians and computer engineers** are a few of the directly related jobs that use the quadratic equation. Others include **engineers, chemists, physicists and even nurses**.

The quadratic equation is used in the design of almost every product in stores today. The equation is used to determine how safe products are and the **life expectancy of products**, such as when they can expect to quit working. Designers can then see what needs to be changed in the product to make it last longer.
