Chapter 14.4, Problem 12PPS

To determine

To find:the given product. And using the models if it is necessary.

Answer to Problem 12PPS

  $2x\left(x+4\right)=2x^2-8x$

Explanation of Solution

Given:

The given product: $2x\left(x+4\right)$

  

Calculation:

As thegiven product is $2x\left(x+4\right)$ .

Simplify the product by open the parenthesis, then

  $\begin{array}{l}2x\left(x+4\right)\\ =2x\left(x\right)-2x\left(4\right)\{\text{open the parenthesis}}\\ =2x^2-8x\{\text{simplify}}\end{array}$

Hence, the value of the given product is $2x\left(x+4\right)=2x^2-8x$ .
