Multiple Choice

Decompose P/Q, Where Q Has Only Distinct Linear Factors
Write the form of the partial fraction decomposition of the rational expression. It is not necessary to solve for the
constants.
1) $\frac { 6 x - 4 } { ( x + 6 ) ( x + 2 ) }$
A) $\frac { A } { x + 6 } + \frac { B } { x + 2 }$
B) $\frac { A } { x + 6 } + \frac { B } { x + 2 } + \frac { C } { ( x + 6 ) ( x + 2 ) }$
C) $\frac { \mathrm { A } } { x + 6 } + \frac { \mathrm { B } } { \mathrm { x } + 2 } + \frac { \mathrm { Cx } + \mathrm { D } } { ( \mathrm { x } + 6 ) ( \mathrm { x } + 2 ) }$
D) $\frac { A } { x + 6 } + \frac { B } { x + 2 } + \frac { C } { ( x + 6 ) ^ { 2 } ( x + 2 ) ^ { 2 } }$
- $\frac { 16 x ^ { 2 } + 68 x + 30 } { x ( x + 3 ) ( x + 5 ) }$

• A) \(\frac { A } { x + 6 } + \frac { B } { x + 2 }\)
• B) \(\frac { A } { x + 6 } + \frac { B } { x + 2 } + \frac { C } { ( x + 6 ) ( x + 2 ) }\)
• C) \(\frac { \mathrm { A } } { x + 6 } + \frac { \mathrm { B } } { \mathrm { x } + 2 } + \frac { \mathrm { Cx } + \mathrm { D } } { ( \mathrm { x } + 6 ) ( \mathrm { x } + 2 ) }\)
• D) \(\frac { A } { x + 6 } + \frac { B } { x + 2 } + \frac { C } { ( x + 6 ) ^ { 2 } ( x + 2 ) ^ { 2 } }\)
• -\(\frac { 16 x ^ { 2 } + 68 x + 30 } { x ( x + 3 ) ( x + 5 ) }\)
• A) \(\frac { 2 } { x } + \frac { 5 } { x + 3 } + \frac { 9 } { x + 5 }\)
• B) \(\frac { 2 } { x } + \frac { 6 } { x + 3 } + \frac { 8 } { x + 5 }\)
• C) \(\frac { 2 } { x } + \frac { 4 } { x + 3 } + \frac { 10 } { x + 5 }\)
• D) \(\frac { x + 5 } { x ^ { 2 } + 3 } + \frac { 9 } { x + 5 }\)
