A) [x299sec1(x3) ]+C\left[ \frac { \sqrt { x ^ { 2 } - 9 } } { 9 } - \sec ^ { - 1 } \left( \frac { x } { 3 } \right) \right] + C
B) 3[x293sec1(x3) ]+C3 \left[ \frac { \sqrt { x ^ { 2 } - 9 } } { 3 } - \sec ^ { - 1 } \left( \frac { x } { 3 } \right) \right] + C
C) 3lnx29(x3) +C3 \ln \left| \sqrt { x ^ { 2 } - 9 } - \left( \frac { x } { 3 } \right) \right| + C
D) 3[x293sin1(x3) ]+C3 \left[ \frac { \sqrt { x ^ { 2 } - 9 } } { 3 } - \sin ^ { - 1 } \left( \frac { x } { 3 } \right) \right] + C
