Special Cases for Multiplying Binomials

We examined three special cases that may exist when multiplying binomials. In one case, we looked for patterns when multiplying examples that followed the rule of (a+b)(a-b), and found the answers followed a predictable pattern; namely a^2 - b^2. When multiplying binomials that expressed the sum squared, or (a+b)(a+b), the answers always followed the rule of a^2 + 2ab + b^2. When multiplying binomials that expressed the difference squared, or (a-b)(a-b), the answers always followed the rule of a^2 - 2ab + b^2.
