9-107.

Simplify each expression.

$\frac { x + 2 } { x ^ { 2 } - 2 x - 3 } + \frac { x } { x ^ { 2 } - 2 x }$
Hint (a):
Review the Math Notes box in Lesson 3.2.5.

$\frac { 2 } { x } - \frac { x } { x - 2 }$
Answer (b):
$\frac{-x^2+2x-4}{x(x-2)}$

$\frac { x ^ { 2 } - x - 6 } { x ^ { 2 } - x - 20 } \cdot \frac { x ^ { 2 } + 6 x + 8 } { x ^ { 2 } - x - 6 }$
Hint (c):
Review the Math Notes box in Lesson 3.2.4.

$\frac { x ^ { 3 } + 8 } { x } \div \frac { x + 2 } { x ^ { 2 } }$
Hint (d):
Review the Math Notes box in Lesson 8.3.3 for a reminder of how to factor the sum of cubes.
