The area of a rectangle is (x^3- 5x^2+ 3x - 15), and the width of the rectangle is. (x^2+ 3). If area = length x width, what is the length
of the rectangle

  (x -5)

Step-by-step explanation:

The area expression can be factored by grouping:

  x^3- 5x^2+ 3x - 15

  = (x^3- 5x^2)+ (3x - 15)

  = x^2(x -5) +3(x -5)

  = (x^2 +3)(x -5)

We recognize the first of these factors as the given width. Then the other factor must be the length.

The length of the rectangle is (x -5).

because they could drop even lower..

your answer is the frist one
