Find the domain of the expression.
-$$\frac { x ^ { 2 } - 25 } { x ^ { 2 } - 6 x + 5 }$$
A) $\{ x \mid x \neq - 5$ and $x \neq + 5 \}$
B) $\{ x \mid x \neq 5$ and $x \neq 1 \}$
C) $\{ x \mid x \neq 0 \}$
D) $\{ x \mid x \neq - 5$ and $x \neq - 1 \}$

The denominator $x^2 - 6x + 5$ factors to $(x-5)(x-1)$, so the expression is undefined when $x = 5$ or $x = 1$, making the domain $\{ x \mid x \neq 5$ and $x \neq 1 \}$.
