Decompose P/Q, Where Q Has a Nonrepeated Prime Quadratic Factor
- $$\frac { 6 x + 4 } { ( x - 1 ) \left( x ^ { 2 } + x + 1 \right) }$$

A) $\frac { \mathrm { A } } { \mathrm { x } - 1 } + \frac { \mathrm { Bx } + \mathrm { C } } { \mathrm { x } ^ { 2 } + \mathrm { x } + 1 }$
B) $\frac { A } { x - 1 } + \frac { B } { x ^ { 2 } + x + 1 }$
C) $\frac { A } { x - 1 } + \frac { B } { x ^ { 2 } + x + 1 } + \frac { C } { ( x - 1 ) \left( x ^ { 2 } + x + 1 \right) }$
D) $\frac { A } { x - 1 } + \frac { B x + C } { x ^ { 2 } + x + 1 } + \frac { D } { ( x - 1 ) \left( x ^ { 2 } + x + 1 \right) }$
