This is one video in the 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. In this 9:45 video, the second of two parts, Blatto-Vallee uses an electronic whiteboard to show several examples of how to find the greatest common factor when factoring polynomials.
