$x = \frac{1}{6},x = - 1$

Step-by-step explanation:

The given rational expresion is

$f(x) = \frac{ - 11x + 1}{ - 30 {x}^{2} - 25x + 5 }$

This expression is undefined, when the denominator is zero.

$- 30 {x}^{2} - 25x + 5 = 0$

Divide through by -5

$6 {x}^{2} + 5x - 1 = 0$

We factor to obtain:

(6x - 1)(x + 1) = 0

Hence the function is undefined when

$x = \frac{1}{6},x = - 1$
