Multiple Choice

The integral x(12) xdx\int x \left( \frac { 1 } { 2 } \right) ^ { x } d x is


A) 2x(xln21) (ln2) 2+C\frac { 2 ^ { x } ( x \ln 2 - 1 ) } { ( \ln 2 ) ^ { 2 } } + C
B) 2x(xln2+1) (ln2) 2+C- \frac { 2 ^ { x } ( x \ln 2 + 1 ) } { ( \ln 2 ) ^ { 2 } } + C
C) (12) x(xln21) (ln2) 2+C- \frac { \left( \frac { 1 } { 2 } \right) ^ { x } ( x \ln 2 - 1 ) } { ( \ln 2 ) ^ { 2 } } + C
D) (12) x(xln2+1) (ln2) 2+C- \frac { \left( \frac { 1 } { 2 } \right) ^ { x } ( x \ln 2 + 1 ) } { ( \ln 2 ) ^ { 2 } } + C
E) (12) x(xln2+1) (ln2) 2+C\frac { \left( \frac { 1 } { 2 } \right) ^ { x } ( x \ln 2 + 1 ) } { ( \ln 2 ) ^ { 2 } } + C
