Chapter 14.2, Problem 21HP

To determine

To evaluate how to add polynomials without using numbers.

Answer to Problem 21HP

Polynomials can be added with the help of algebra tiles.

Explanation of Solution

Given information:

Polynomial addition

Formula used: Polynomial addition

Calculation:

Let, 2x² and x²+1 be the polynomials which needs to be added.

Hence,

2x²+(x²+1)

Here, 2x² is represented by two blue tiles and x²+1 is represented by 1blue and one yellow tile.

  

On solving, 2x² and x² adds,

Result, is 3x²+1
