The area of a rectangle swimming pool is 10x^2-19x-15. The length of the pool is 5x+3. What is the width of the pool?

To find the width of the pool, we need to divide the total area by the length.

Width = Area / Length
Width = (10x^2 - 19x - 15) / (5x + 3)

Now we will divide the polynomial by the length:

(10x^2 - 19x - 15) / (5x + 3) = 2x - 5

Therefore, the width of the pool is 2x - 5.
