Chapter 8.4, Problem 34P

Simplify each product.

$(m+1)(m-1)$

To determine

To simplify: The product $\left(m+1\right)\left(m-1\right)$ .

Answer to Problem 34P

  $m^2-1$

Explanation of Solution

Given information:

The expression is $\left(m+1\right)\left(m-1\right)$ .

Calculation:

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

  $\begin{array}{c}\left(m+1\right)\left(m-1\right)=m^2-1^2\\ =m^2-1\end{array}$
