Chapter 0.2, Problem 10E

To determine

the product.

Answer to Problem 10E

  $\left(x-15\right)\left(x-15\right)=x^2-30x+225$

Explanation of Solution

Given information:

  $\left(x-15\right)\left(x-15\right)$

It is given that $\left(x-15\right)\left(x-15\right)$

So,

  $\begin{array}{c}\left(x-15\right)\left(x-15\right)=x\left(x-15\right)-15\left(x-15\right)\\ x\left(x-15\right)-15\left(x-15\right)=x^2-15x-15x+225\\ x^2-15x-15x+225=x^2-30x+225\end{array}$

So,

  $\left(x-15\right)\left(x-15\right)=x^2-30x+225$
