Chapter 14.3, Problem 11PPS

To determine

Subtract the given equations,

(-4x²+x+5) - (x²+ 2x +3)

Explanation of Solution

Given information:

Polynomials,

(-4x²+x+5) - (x²+ 2x +3)

Formula used: Algebra Tiles

Calculation:

Opening the bracket of the given equation,

-4x²+x+5- x²- 2x -3

Here, 7x is represented by 7 green tiles, -5 is represented by 5 red tiles, -2x is represented by 2 red tiles and 1 is represented by 1 yellow tile.

  

On solving, -4x² and -x² adds, x and -2x subracts and 5 and -3 subtracts.

  

Result, is 5x²-x+2
