$x = 0 , x = - 10 \text{, are the Excluded Values.}$

#### Explanation:

The Exp.$= \frac{x + 10}{8 {x}^{2} + 80 x} = \frac{x + 10}{8 x \left(x + 10\right)}$

So, when, $x = 0 , \mathmr{and} , x = - 10 \text{, the Dr.=0}$.

As Division by $0$ is not permitted in Mathematics, we get these

values as the Excluded Values for the given Rational Exp.

$\therefore x = 0 , x = - 10 \text{, are the Excluded Values.}$
