Exercise 15 Page 206

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

Terms: g, 12 and 9g
Coefficients: 1 and 9
Constants: 12

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.

g + 12 + 9g We can see that the expression has three terms, g, 12 and 9g. 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. g+12+9g ⇕ 1g+ 12+ 9g The expression has two coefficients, which are 1 and 9, and a constant, which is 2. Let's organize this information in a table.

Terms	Coefficients	Constants
g, 12 and 9g	1 and 9	12
