2a)

To verify, set the factors to zero.

(x - 2) = 0, x = 2

(x + 3) = 0, x = -3

Insert zero's in the equation:

<u>when x = 2</u>

3(2)³ + 2(2)² - 19(2) + 6 = 0

<u>when x = -3</u>

3(-3)³ + 2(-3)² - 19(-3) + 6 = 0

Hence verified the factors.

2b)

= \sf \dfrac{\left(3x^3+2x^2-19x+6\right)}{\left(x-2\right)\left(x+3\right)}

\sf = \dfrac{\left(3x-1\right)\left(x-2\right)\left(x+3\right)}{\left(x-2\right)\left(x+3\right)}

\sf = 3x -1

The remaining factor is (3x - 1)

2c)

Set the factors to zero to find real zeros of f

  • (3x - 1) = 0, x = 1/3
  • (x - 2) = 0, x = 2
  • (x + 3) = 0, x = -3

2d)

<u>Complete factorization</u>: (3x - 1)(x - 2)(x + 3)

Wes measures the floor area of his rectangular living room to replace the carpet with tiles.The room is 12.4 feet long and 9.8 f
Zina [86]

Answer: 121.52 square feets

Step-by-step explanation:

The room has the shape of a rectangle and its dimensions are 12.4 feet long and 9.8 feet wide. This means that dimension of the carpet is also 12.4 feet long and 9.8 feet wide. To replace the rectangular carpet with tiles, the area of the tiles must be equal to the area of the carpet. The area of the carpet is determined by length × width.

Length of the room or carpet = 12.4 feets

Width of the room or carpet = 9.8 feets

The number of square feets of tiles that Wes will need

=12.4 ×9.8 = 121.52 square feets
