The area of a rectangular swimming pool is 10x2 – 19x – 15. The length of the pool is 5x + 3.the length of the pool is 5x + 3

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

The area of the pool is 10x^2 - 19x - 15.
The length of the pool is 5x + 3.

So, the width is (10x^2 - 19x - 15) / (5x + 3).

This cannot be simplified any further, so the width of the pool is (10x^2 - 19x - 15) / (5x + 3).
