When we apply a square root to both sides of an equation, we introduce two solutions. We discuss why there must be two solutions, and illustrate practical examples of these types of equations. Equations in projectile motion in physics are quadratic in nature. Einstein's famous equation E=mc^2 is also has a square on the speed of light.
