Multiple Choice

Write the partial fraction decomposition of the rational expression.
- $$\frac { 3 x ^ { 3 } + 3 x ^ { 2 } + 4 x + 6 } { \left( x ^ { 2 } + 3 \right) ^ { 3 } }$$

• A) \(\frac { 3 x + 3 } { \left( x ^ { 2 } + 3 \right) ^ { 2 } } + \frac { - 5 x - 3 } { \left( x ^ { 2 } + 3 \right) ^ { 3 } }\)
• B) \(\frac { x + 1 } { x ^ { 2 } + 3 } + \frac { 3 x + 3 } { \left( x ^ { 2 } + 3 \right) ^ { 2 } } + \frac { - 5 x - 3 } { \left( x ^ { 2 } + 3 \right) ^ { 3 } }\)
• C) \(\frac { 3 x - 3 } { \left( x ^ { 2 } + 3 \right) ^ { 2 } } + \frac { - 5 x + 3 } { \left( x ^ { 2 } + 3 \right) ^ { 3 } }\)
• D) \(\frac { x } { x ^ { 2 } + 3 } + \frac { 3 x + 3 } { \left( x ^ { 2 } + 3 \right) ^ { 2 } } + \frac { - 5 x - 3 } { \left( x ^ { 2 } + 3 \right) ^ { 3 } }\)
