Question 293

Multiple Choice

Express the integrand as a sum of partial fractions and evaluate the integral.
- 2x2+8x+8(x2+4) (x2) 3dx\int \frac { - 2 x ^ { 2 } + 8 x + 8 } { \left( x ^ { 2 } + 4 \right) ( x - 2 ) ^ { 3 } } d x


A) 12tan1(x2) +lnx21(x2) 2+C\frac { 1 } { 2 } \tan ^ { - 1 } \left( \frac { x } { 2 } \right) + \ln | x - 2 | - \frac { 1 } { ( x - 2 ) ^ { 2 } } + C
B) 12tan1(x2) +1x21(x2) 2+C\frac { 1 } { 2 } \tan ^ { - 1 } \left( \frac { x } { 2 } \right) + \frac { 1 } { x - 2 } - \frac { 1 } { ( x - 2 ) ^ { 2 } } + C
C) tan1(x2) 2x21(x2) 2+C\tan ^ { - 1 } \left( \frac { x } { 2 } \right) - \frac { 2 } { x - 2 } - \frac { 1 } { ( x - 2 ) ^ { 2 } } + C
D) 12tan1(x2) 1(x2) 2+1(x2) 3+C\frac { 1 } { 2 } \tan ^ { - 1 } \left( \frac { x } { 2 } \right) - \frac { 1 } { ( x - 2 ) ^ { 2 } } + \frac { 1 } { ( x - 2 ) ^ { 3 } } + C
