What is the Product of Two Expressions?

The product of two expressions is the result of multiplying those expressions together. In the given problem, we are asked to find the product of two expressions: $-b$ and $(-4b^3 + 5)$ . To find the product, we need to multiply these two expressions together.

How to Multiply Expressions

To multiply expressions, we need to follow the order of operations (PEMDAS):

Parentheses: Evaluate expressions inside parentheses first.
Exponents: Evaluate any exponential expressions next.
Multiplication and Division: Evaluate any multiplication and division operations from left to right.
Addition and Subtraction: Finally, evaluate any addition and subtraction operations from left to right.

Step-by-Step Solution

Let's break down the solution step by step:

Step 1: Multiply the First Term

The first term is $-b$ . To multiply this term by the second expression, we need to multiply $-b$ by each term inside the parentheses.

-b × (-4b^3) = 4b^4
-b × 5 = -5b

Step 2: Combine Like Terms

Now, we need to combine like terms. In this case, we have two terms with the same variable, $b$ . We can combine these terms by adding or subtracting their coefficients.

4b^4 - 5b

Step 3: Simplify the Expression

The expression is already simplified, so we don't need to do anything else.

Final Answer

The final answer is: $\boxed{4b^4 - 5b}$
