Multiple Choice

Write the form of the partial fraction decomposition of the rational expression.Do not solve for the constants.​ $$\frac { x - 4 } { x \left( x ^ { 2 } + 7 \right) ^ { 2 } }$$ ​

• A) \(\frac { A } { x } + \frac { B } { x ^ { 2 } + 7 } + \frac { C } { \left( x ^ { 2 } + 7 x ^ { 4 } \right) ^ { 2 } }\) ​
• B) \(\frac { A } { x } + \frac { B x + C } { x ^ { 2 } + 7 } + \frac { D x + E } { ( x + 7 ) ^ { 2 } }\) ​
• C) \(\frac { A } { x } - \frac { B x + C } { \left( x ^ { 2 } + 7 \right) ^ { 2 } } - \frac { D x + E } { x \left( x ^ { 2 } + 7 \right) ^ { 2 } }\) ​
• D) \(\frac { A } { x } + \frac { B x + C } { x ^ { 2 } + 7 } + \frac { D x + E } { \left( x ^ { 2 } + 7 \right) ^ { 2 } }\) ​
• E) \(\frac { A } { x - 4 } + \frac { B x + C } { x ^ { 2 } + 7 } + \frac { D x + E } { \left( x ^ { 2 } + 7 \right) ^ { 2 } }\)
