Chapter 14.1, Problem 3BGP

To determine

To simplify polynomial

Explanation of Solution

Given information:

Polynomial $-2x^2+5-1+x^2$

Here, - $2x^2$ is represented by 2 red tiles, $x^2$ is represented by 1 blue tiles and 5 is represented as 5 yellow tiles and -1 as represented as 1 red tile.

  

        -2x²      5      -1          x²

On solving. -2x² and x² subtracts and 5 and 1 also subtracts

  

Result is $-x^2+4$

  

      x²        4
