Exercise 17 Page 206

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

Terms: 2m^2, 15 and 2p^2
Coefficients: 2 and 2
Constants: 15

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. 2m^2 + 15 + 2p^2

We can see that the expression has three terms, 2m^2, 15 and 2p^2. 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. 2m^2+ 15+ 2p^2 The expression has two coefficients, which are 2 and 2, and a constant, which is 15. Let's organize this information in a table.

Terms	Coefficients	Constants
2m^2, 15 and 2p^2	2 and 2	15
