Multiple Choice

Find the vertical asymptotes of the rational function.
- $$f ( x ) = \frac { x ( x - 1 ) } { 49 x ^ { 2 } + 84 x + 20 }$$

A) $x = \frac { 2 } { 7 } , x = \frac { 10 } { 7 }$
B) $x = - \frac { 1 } { 25 } , x = - \frac { 3 } { 25 }$
C) $\mathrm { x } = - \frac { 10 } { 49 } , x = \frac { 30 } { 49 }$
D) $x = - \frac { 1 } { 5 } , x = - \frac { 3 } { 5 }$
