WebThe values of a and b could have been directly substituted in the algebraic expression (a + b) 2 as shown below: (a + b) 2 = (2 + 3) 2. = 5 2. = 25. Which is the same result found earlier. Another example could be: Evaluate (a + b) 2 - (a - b) 2 when a = 5 and b = 2. Substituting the values of a and b in the expression gives: Web(a−b)(a2 +ab+b2) a2 − b2 ( a - b) ( a 2 + a b + b 2) a 2 - b 2 Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (a+b)(a−b) a 2 - b 2 = ( a + b) ( a - b) where a = a a = a and b = b b = b. (a−b)(a2 +ab+b2) (a+b)(a −b) ( a - b) ( a 2 + a b + b 2) ( a + b) ( a - b) Cancel the common factor of a−b a - b.
