The expression you provided is:

$5x - \frac{5}{(x-3)(x^2 - 5x + 6)}$

First, let's simplify this step-by-step.

Step 1: Factor the denominator

Start by factoring the quadratic in the denominator:

$x^2 - 5x + 6 = (x-2)(x-3)$

So the expression becomes:

$5x - \frac{5}{(x-3)(x-2)(x-3)}$

Step 2: Simplify the denominator

The denominator includes $(x-3)(x-3)$, which simplifies to $(x-3)^2$. Thus, the expression now looks like:

$5x - \frac{5}{(x-3)^2(x-2)}$

Final simplified form:

$5x - \frac{5}{(x-3)^2(x-2)}$

This is as simplified as it gets unless further specific conditions or operations (like factoring the numerator or performing partial fractions) are required.
