Exercise 19 Page 206

Terms are separated by + or - signs. Coefficients are numbers that are multiplied by variables. Constants are numbers with no variable factors.

Terms: 8x and x^23
Coefficients: 8 and 13
Constants: None

Practice makes perfect

An algebraic expression is a combination of numbers, variables, and mathematical operations. Terms are separated by + or - signs. With this information in mind, let's identify the terms in the given expression. 8x + x^2/3

We can see that the expression has two terms, 8x and x^23. Next, we will identify the coefficients and constants. A coefficient is a number that is multiplied by a variable or variables. Variables on their own, without a number next to them, actually have a coefficient of 1. A constant is a number with no variable factors. 8x+x^2/3 ⇕ 8x+ 1/3x^2 The expression has two coefficients, which are 11, and no constants. Let's organize this information in a table.

Terms	Coefficients	Constants
8x and x^23	8 and 13	None
