Video illustrates the pattern of multiplying binomials of the form (a + b)(a - b). Applies the pattern to multiply (2x + 8)(2x -8). [2:29]

Video explains how to find special binomial products. Four examples are worked that show how to square a binomial. Three examples are worked that show the product of a sum and a difference (a +b)(a - b). This video also appears in the...
