Ch 2 Sec 2B: Slide #5 CAUTION It is important to be able to distinguish between terms and factors. For example, in the expression 5x 3 + 4x 3, there are two terms, 5x 3 and 4x 3. Terms are separated by a + or – sign. On the other hand, in the one-term expression ( 5x 3 )( 4x 3 ), 5x 3 and 4x 3 are factors. Factors are multiplied.
Ch 2 Sec 2B: Slide #6 CAUTION Remember that only like terms may be combined.
