Chapter 0, Problem 9PR

To determine

The product of the given expression.

Answer to Problem 9PR

The product is $c^2-64$ .

Explanation of Solution

Given information:

The given expression is:

  $(c+8)(c-8)$ .

Calculation:

The given expression is:

  $(c+8)(c-8)$ .

By multiplying the expression,

  $\begin{array}{l}(c+8)(c-8)\\ =c(c-8)+8(c-8)\\ =c^2-8c+8c-64\\ =c^2-64\end{array}$

  $\therefore$ The product is $c^2-64$ .
