Chapter 14.3, Problem 8PPS

To determine

Subtract the given equations,

( x²+ 8x - 9) - ( 3x - 1)

Explanation of Solution

Given information:

Polynomials,

( x²+ 8x - 9) - ( 3x - 1)

Formula used: Algebra Tiles

Calculation:

Opening the bracket of the given equation,

( x²+ 8x - 9) - ( 3x - 1)

Here, x² is represented by blue tile, 9x is represented by 9 green tiles, -9is represented by 9 red tiles, -3x is represented by 3 yellow tiles and 1 is represented by yellow tile.

  

On solving, 8x and -3x subracts and -9 and 1 also subtracts.

  

Result, is x²+5x-8
