Question 22

Multiple Choice

Find the partial fraction decomposition.
- x+2x21=Ax+1+Bx1\frac { x + 2 } { x ^ { 2 } - 1 } = \frac { A } { x + 1 } + \frac { B } { x - 1 }


A) A=12, B=32\mathrm { A } = - \frac { 1 } { 2 } , \mathrm {~B} = \frac { 3 } { 2 }
B) A=12, B=32\mathrm { A } = \frac { 1 } { 2 } , \mathrm {~B} = - \frac { 3 } { 2 }
C) A=12,B=32A = - \frac { 1 } { 2 } , B = - \frac { 3 } { 2 }
D) A=12, B=32\mathrm { A } = \frac { 1 } { 2 } , \mathrm {~B} = \frac { 3 } { 2 }
