Question 206

Multiple Choice

Find the partial fraction decomposition for the rational expression.
2x35x21x+7(x1) 3(x+2) \frac { 2 x ^ { 3 } - 5 x ^ { 2 } - 1 x + 7 } { ( x - 1 ) ^ { 3 } ( x + 2 ) }


A) 1x1+1(x1) 2+2(x1) 3+1x+2\frac { 1 } { x - 1 } + \frac { - 1 } { ( x - 1 ) ^ { 2 } } + \frac { 2 } { ( x - 1 ) ^ { 3 } } + \frac { - 1 } { x + 2 }
B) 1x1+2(x1) 2+1(x1) 3+1x+2\frac { 1 } { x - 1 } + \frac { 2 } { ( x - 1 ) ^ { 2 } } + \frac { 1 } { ( x - 1 ) ^ { 3 } } + \frac { 1 } { x + 2 }
C) 1x1+2(x1) 2+1(x1) 3+1x+2\frac { 1 } { x - 1 } + \frac { - 2 } { ( x - 1 ) ^ { 2 } } + \frac { 1 } { ( x - 1 ) ^ { 3 } } + \frac { 1 } { x + 2 }
D) 1x1+1(x1) 2+2(x1) 3+1x+2\frac { 1 } { x - 1 } + \frac { - 1 } { ( x - 1 ) ^ { 2 } } + \frac { - 2 } { ( x - 1 ) ^ { 3 } } + \frac { 1 } { x + 2 }
