Applications of Factoring

 

 

1.

The room that is shown in the figure below has a floor space of 2x² + x - 15 square feet.  If the width of the room is (x + 3) feet, what is the length?

Choose:

(x - 3)
(2x - 5)
(x - 5)
(2x + 5)

 

 

2.

Interpret the factoring model shown below:
(College Algebra by Larson, Hostetler, Hodgkins)

 

Choose:

a² + b²  becomes  (a + b)(a + b)
a² - b²   becomes  (a + b)(a - b)
a² - b²   becomes  (a b)(a - b)
a² + b²  becomes  (a b)(a - b)
