Introduction to Topic 6.2 - Extracting the Square Roots

What takes longer to hit the ground, a cotton ball or a rubber ball that is the same size and shape? If air resistance is ignored, they will fall to the Earth at about the same rate. This lesson will focus using square roots to solve quadratic models such as the ones that model how long it takes for an object to fall to Earth.

Essential Question(s): How can square roots be used to find the solutions to a quadratic equation?
