The expression you provided is:

$\frac{2x^2 - 10x}{6x - 30}$

Step-by-Step Simplification:

1. Factor the numerator and the denominator:

   • The numerator is $2x^2 - 10x$. You can factor out the common factor of $2x$: $2x^2 - 10x = 2x(x - 5)$

   • The denominator is $6x - 30$. You can factor out the common factor of $6$: $6x - 30 = 6(x - 5)$

2. Rewrite the expression:

   The expression now becomes: $\frac{2x(x - 5)}{6(x - 5)}$

3. Cancel the common factor $(x - 5)$ from the numerator and the denominator (as long as $x \neq 5$, to avoid division by zero): $\frac{2x(x - 5)}{6(x - 5)} = \frac{2x}{6}$

4. Simplify the fraction $\frac{2x}{6}$ to $\frac{x}{3}$.

Thus, the simplified form of the expression is: $\frac{x}{3}$

Final Answer:

$\frac{2x^2 - 10x}{6x - 30} = \frac{x}{3} \quad \text{(as long as } x \neq 5)$
