Multiple Choice

Find the partial fraction decomposition for the rational expression.
- $$\frac { x ^ { 2 } } { x ^ { 2 } + 6 x + 9 }$$

A) $\frac { 6 } { x + 3 } + \frac { - 6 } { ( x + 3 ) ^ { 2 } }$

B) $\frac { - 6 } { x + 3 } + \frac { 9 } { ( x + 3 ) ^ { 2 } }$

C) $1 + \frac { 6 } { x + 3 } + \frac { - 9 } { ( x + 31 ) ^ { 2 } }$

D) $1 + \frac { - 6 } { x + 3 } + \frac { 9 } { ( x + 3 ) ^ { 2 } }$
