Exercise 14 Page 95

Terms are separated by + signs.

Terms: 12s, - 4, 34s, 18, - s^3
Like Terms: 12s and 34s, - 4 and 18

Practice makes perfect
An algebraic expression is a combination of numbers, variables, and mathematical operations. Terms are separated by + signs. With this information in mind, let's identify the terms in the given expression. We will first rewrite it as a sum of terms.

1/2s - 4 + 3/4s + 1/8 - s^3 ⇓ 1/2s + ( - 4) + 3/4s + 1/8 + ( - s^3) We can see that the expression has five terms, 12s, - 4, 34s, 18, - s^3. Now that we know the terms, we can figure out which ones are like terms. Remember, like terms are terms that have the same variable and the same exponent. In this case, 12s and 34s are like terms as well as - 4 and 18.
