KEY CONCEPTS: Difference of squares are binomials with the function of subtraction separating the 2 terms. NEVER a positive value. When Factoring such special quadratics: i.) square root the first term and the second term ii.) place the first value as the first term of 2 sets of binomials and the second value as the second term iii.) in one set of binomials write a negative, and the second set a positive. ie. x^2-81 = (x+9)(x-9)
