Question 315

Multiple Choice

Find the partial fraction decomposition.
- 7x(3x1) (x+1) =Ax+B3x1+Cx+1\frac { - 7 } { x ( 3 x - 1 ) ( x + 1 ) } = \frac { A } { x } + \frac { B } { 3 x - 1 } + \frac { C } { x + 1 }


A) A=7, B=634,C=74\mathrm { A } = - 7 , \mathrm {~B} = \frac { 63 } { 4 } , \mathrm { C } = \frac { 7 } { 4 }
B) A=7, B=634,C=74\mathrm { A } = 7 , \mathrm {~B} = \frac { 63 } { 4 } , \mathrm { C } = \frac { 7 } { 4 }
C) A=7, B=634,C=74\mathrm { A } = 7 , \mathrm {~B} = - \frac { 63 } { 4 } , \mathrm { C } = - \frac { 7 } { 4 }
D) A=7,B=634,C=74A = - 7 , B = - \frac { 63 } { 4 } , C = - \frac { 7 } { 4 }
