Exercise 1 Page 235

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

Terms: 9x, 8y, and 2
Coefficients: 9 and 8
Constants: 2

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. 9x + 2 + 8y

We can see that the expression has three terms, 9x, 2, and 8y. Next, we will identify the coefficients and constants. A coefficient is a number that is multiplied by a variable or variables. A constant is a number with no variable factors. 9x+ 2+ 8y The expression has two coefficients, which are 9 and 8, and a constant, which is 2. Let's organize this information in a table.

Terms	Coefficients	Constants
9x, 8y, and 2	9, 8	2
