Problem 70 - Introductory Algebra for College Students

Question

Identify the terms in each algebraic expression. $$-9 a-4 b$$

Step-by-Step Solution

Answer

The terms in the algebraic expression are -9a and -4b.

Step 1: Identify Terms

In the given algebraic expression \( -9a - 4b \), the terms are separated by the addition or subtraction operators. Here we only have subtraction. Therefore, we can visually separate this into two parts. The first term is \( -9a \) and the second term is \( -4b \). Note that a term includes both the number (which can be called the coefficient in this context) and the variable.

Step 2: Identify the algebraic structure

Determine the type of algebraic problem.

Step 3: Apply algebraic techniques

Use factoring, expanding, or systematic methods.

Step 4: Simplify and solve

Simplify expressions and solve for unknowns.

Step 5: State the result

Write the final answer.

Step 6: Conclude with the answer

The terms in the algebraic expression are -9a and -4b.
