Question 24

Multiple Choice

Write the partial fraction decomposition of the rational expression. x2x423x250\frac { x ^ { 2 } } { x ^ { 4 } - 23 x ^ { 2 } - 50 }


A) ​ 1x216x210\frac { 1 } { x ^ { 2 } } - \frac { 1 } { 6 } - \frac { x ^ { 2 } } { 10 }
B) 127(2x2+2+52(x5) 52(x+5) ) \frac { 1 } { 27 } \left( \frac { 2 } { x ^ { 2 } + 2 } + \frac { 5 } { 2 ( x - 5 ) } - \frac { 5 } { 2 ( x + 5 ) } \right)
C) 127(2x2+2+5(x+2) 2(x5) +52(x5) ) \frac { 1 } { 27 } \left( \frac { 2 } { x ^ { 2 } + 2 } + \frac { 5 ( x + 2 ) } { 2 ( x - 5 ) } + \frac { 5 } { 2 ( x - 5 ) } \right)
D) 127(2x2+252(x5) +52(x+5) ) \frac { 1 } { 27 } \left( \frac { 2 } { x ^ { 2 } + 2 } - \frac { 5 } { 2 ( x - 5 ) } + \frac { 5 } { 2 ( x + 5 ) } \right)
E) 127(2x2+2+52(x5) 52(x+5) ) \frac { 1 } { 27 } \left( \frac { 2 } { x ^ { 2 } + 2 } + \frac { 5 } { 2 ( x - 5 ) } - \frac { 5 } { 2 ( x + 5 ) } \right)
