Multiple Choice

Write the partial fraction decomposition of the rational expression.
- 6x3+4x2+13x+15(x2+3) 3\frac { 6 x ^ { 3 } + 4 x ^ { 2 } + 13 x + 15 } { \left( x ^ { 2 } + 3 \right) ^ { 3 } }


A) xx2+3+6x+4(x2+3) 2+5x+3(x2+3) 3\frac { x } { x ^ { 2 } + 3 } + \frac { 6 x + 4 } { \left( x ^ { 2 } + 3 \right) ^ { 2 } } + \frac { - 5 x + 3 } { \left( x ^ { 2 } + 3 \right) ^ { 3 } }
B) x+1x2+3+6x+4(x2+3) 2+5x+3(x2+3) 3\frac { x + 1 } { x ^ { 2 } + 3 } + \frac { 6 x + 4 } { \left( x ^ { 2 } + 3 \right) ^ { 2 } } + \frac { - 5 x + 3 } { \left( x ^ { 2 } + 3 \right) ^ { 3 } }
C) 6x4(x2+3) 2+5x3(x2+3) 3\frac { 6 x - 4 } { \left( x ^ { 2 } + 3 \right) ^ { 2 } } + \frac { - 5 x - 3 } { \left( x ^ { 2 } + 3 \right) ^ { 3 } }
D) 6x+4(x2+3) 2+5x+3(x2+3) 3\frac { 6 x + 4 } { \left( x ^ { 2 } + 3 \right) ^ { 2 } } + \frac { - 5 x + 3 } { \left( x ^ { 2 } + 3 \right) ^ { 3 } }
