Chapter 14.1, Problem 17PPS

To determine

To simplify polynomial

Explanation of Solution

Given information:

Polynomial $-x^2+3x+x^2-2x$

Here, - x² is represented 1 red tile and 3x is represented by green tiles and x² is represented by 1 blue tile and - 2x is represented by 2 red tiles.

  

On solving, x² and − x² subtracts, 3x and - 2x also subtracts making,

  

Result is x
