Algebra: A Combined Approach (4th Edition)

The answer to problem #5 is: "A number term is also called a constant." So, the answer is "constant." If a polynomial contains a term that is merely a number, it is known as a constant. Example: $x^{2} + 4x + 3$ There are three terms in this example. Term #1: $x^{2}$ Term #2: $4x$ Term #3: $3$ The 3rd term in this example is only a number, $3$, which marks it as a "constant." In other words, it can't be modified by any other variable.
