Use Division to Write the Rational Function in the Form $$\frac { 4 x ^ { 3 } + 8 x ^ { 2 } + 5 x - 7 } { 2 x ^ { 2 } - x - 1 }$$

Use division to write the rational function in the form q(x) + r(x) /d(x) , where the degree of r(x) is less than the degree of
d(x) . Then find the partial fraction decomposition of r(x) /d(x) .
- $$\frac { 4 x ^ { 3 } + 8 x ^ { 2 } + 5 x - 7 } { 2 x ^ { 2 } - x - 1 }$$

A) $2 x + 5 + \frac { 16 / 3 } { 2 x + 1 } + \frac { 10 / 3 } { x - 1 }$
B) $2 x - 5 - \frac { 5 / 3 } { 2 x + 1 } + \frac { 1 / 3 } { x - 1 }$
C) $2 x + 5 - \frac { 7 / 3 } { 2 x + 1 } + \frac { 13 / 3 } { x - 1 }$
D) $2 x - 5 + \frac { 13 } { 2 x + 1 } + \frac { 7 } { x - 1 }$
