Chapter 8.3, Problem 12P

Simplify each product using a table.

$(w-4)(w+8)$

To determine

To simplify: The provided expression.

Answer to Problem 12P

The solution is $w^2+4w-32$

Explanation of Solution

Given:

The expression is:

  $\left(w-4\right)\left(w+8\right)$

Calculation:

Here, expressions $\left(w-4\right)\left(w+8\right)$

could be simplified as:

  $\begin{array}{c}\left(w-4\right)\left(w+8\right)=w\times w+8w-4w-32\\ =w^2+4w-32\end{array}$

Hence, the obtained solution is $w^2+4w-32$
