(12 a3) 2 (12 a3) 2 = 144 a 272 a + 9 = (12 a ) 22(12 a )(3) + (3) 2 MartinGay, Beginning Algebra, 5ed 6 Sum and Difference of Two Terms Multiplying the Sum and Difference of Two Terms The product of the sum and difference of two terms is the square of the first term minus the square of the second term. ( a + b )( a b ) = a 2 b 2 Example: Multiply. (5 a + 3)(5 a3) (5 a + 3)(5 a3) = 25 a 29 = (5 a ) 23 2 MartinGay, Beginning Algebra, 5ed 7 Although you will arrive at the same results for the special products by using the techniques of this section or last section, memorizing these products can save you some time in multiplying polynomials.
