Use Division to Write the Rational Function in the Form 5x2−x−10x2−4\frac { 5 x ^ { 2 } - x - 10 } { x ^ { 2 } - 4 }

Question 98

Multiple Choice

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) .
- 5x2−x−10x2−4\frac { 5 x ^ { 2 } - x - 10 } { x ^ { 2 } - 4 }


A) 5+2x−2−3x+25 + \frac { 2 } { x - 2 } - \frac { 3 } { x + 2 }
B) 2x−2−3x+2\frac { 2 } { x - 2 } - \frac { 3 } { x + 2 }
C) 5+3x−2−2x+25 + \frac { 3 } { x - 2 } - \frac { 2 } { x + 2 }
D) 5+2x−2+3x−25 + \frac { 2 } { x - 2 } + \frac { 3 } { x - 2 }
