Quadratic Equations

This webpage includes two quadratic equation videos that are a part of a series of lessons on math provided by DeafTEC. Gary Blatto-Vallee, a math and science instructor at the National Technical Institute for the Deaf, guides viewers through a variety of mathematical exercises in this DeafTEC video series. All lessons are fully captioned, signed in ASL, and voiced. The two videos provided here teach students how to solve quadratic equations using the square root property.Â
