Chapter 14.2, Problem 1CYU

To determine

To add polynomial

Explanation of Solution

Given information:

Polynomial $(x+5)+(2x+3)$

Opening brackets,

  $x+5+2x+3$

Here, $x$ and 2 $x$ is represented by 1 and 2 green tiles respectively. 5 and 3 are represented by 5 and 3 yellow tiles respectively.

  

On solving, $x$ and 2 $x$ add, 5and 3 add, resulting

  

8 Result is 3 $x$ + 8
