Chapter 8.4, Problem 31P

Simplify each product.

$(x+12)(x-12)$

To determine

To simplify: The product $\left(x+12\right)\left(x-12\right)$ .

Answer to Problem 31P

  $x^2-144$

Explanation of Solution

Given information:

The expression is $\left(x+12\right)\left(x-12\right)$ .

Calculation:

Use the difference of squares that is., $\left(x+y\right)\left(x-y\right)=x^2-y^2$

  $\begin{array}{c}\left(x+12\right)\left(x-12\right)=x^2-{12}^2\\ =x^2-144\end{array}$
