Chapter 8.4, Problem 33P

Simplify each product.

$(t-15)(t+15)$

To determine

To simplify: The product $\left(t-15\right)\left(t+15\right)$ .

Answer to Problem 33P

  $t^2-225$

Explanation of Solution

Given information:

The expression is $\left(t-15\right)\left(t+15\right)$ .

Calculation:

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

  $\begin{array}{c}\left(t-15\right)\left(t+15\right)=t^2-{15}^2\\ =t^2-225\end{array}$
