The image shows a mathematical expression involving fractions. The expression is:

$\frac{1}{b-5} - \frac{1}{b-3} + \frac{1}{b+5} - \frac{1}{b+3}$

To solve or simplify this expression, we need to combine the fractions. The least common denominator (LCD) will be the product of all distinct denominators: $(b-5)(b-3)(b+5)(b+3)$.

Let's proceed with finding the solution.
