Chapter 8.4, Problem 1STP

Solve each exercise and enter your answer on the grid provided.

What is coefficient of the $x$-term in the simplified form of ${(2x+4)}^2$?

To determine

To find the coefficient of x.

Answer to Problem 1STP

16.

Explanation of Solution

Given:

  ${\left(2x+4\right)}^2$

Calculation:

The solution can be obtained as:

  $\begin{array}{l}{\left(2x+4\right)}^2={\left(2x\right)}^2+2\left(2x\right)\left(4\right)+{\left(4\right)}^2\\ =4x^2+16x+16\end{array}$

Therefore coefficient of x is 16.
