Identify the constants and variables of each term. Each expression being multiplied is a separate factor. Note that each constant factor is considered one factor. The term 3xy consists of 3 multiplied by x and y. Thus, there are three factors: 3, x, and . The term 9x2y consists of 9 multiplied by x2 and y. The expression x2 is actually (x x). When part of a variable term, however, x2 is treated as just one factor. Thus, there are three factors: 9, , and y. The term 7x consists of 7 multiplied by x. Thus, there are two factors: and x. The term 5 consists of the single constant 5. Thus, there is just one factor: . Notice that 9, 8, 6 and 4 can be written as 22, 23, 2 3, or 22, respectively. Therefore, 9, 8, 6 and 4 can be thought of as more than one factor. When part of a variable expression, though, each constant term is considered just one factor. The only term with two factors is
