Find All Values That Make the Rational Expression Undefined $$\frac { x ^ { 3 } + 5 x ^ { 4 } } { x ^ { 2 } + 36 }$$

Find all values that make the rational expression undefined. If the rational expression is defined for all real numbers, so
state.
- $$\frac { x ^ { 3 } + 5 x ^ { 4 } } { x ^ { 2 } + 36 }$$

A) $x = - 36$
B) $x = 0 , x = - \frac { 1 } { 5 }$
C) $x = - 6$
D) Defined for all real numbers
