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)

DochEvi [55]

Answer:

The expression for the length of the rectangle is 2x + 4

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = length × width

The area of a rectangle is expressed as (14x + 28) square feet. If the width of the rectangle is 7 feet, then the expression for the length of the rectangle would be

Length = Area/ width

= (14x + 28)/7

The numerator has a common factor of 7. Therefore, if we factorize 7 out, it becomes

7(2x + 4)/7

Length = 2x + 4
