1. The problem statement, all variables and given/known data is an expression that is a difference of two squares considered to be a quadratic. For example, would x2 - 4 be a quadratic? What about x4 - 4? 2. Relevant equations Ax2 + Bx + C 3. The attempt at a solution I know we can factor a DOTS into two binomials like a quadratic in the for Ax2 + Bx + C, but I wanted to be clear on what a DOTS was relative to a quadratic equation.
