## Rational Functions

A rational function can have a variable like "x" in the numerator AND the denominator. When this happens, there are some special rules and properties to consider.

# Rational Equations

Solve the following for $$x$$:

$\frac{ x-14 } { x - 7 } = 1 + \frac{ 14 } { x - 28}.$

Solve for $$x$$:

$\frac{5}{x } + \frac{ 3x + 8 }{ x^2 - 8 x } = \frac{7 x + 8 }{ x^2- 8 x} .$

Solve the following for $$x:$$

$\frac{ 28 } { x^2 - 4x } = 1 + \frac{ 7 } { x - 4}.$

How many solutions are there for

$\frac { 18 }{ x^2 + 18x } + \frac{ 18 }{ x^2 + 54x + 648 } = - \frac{ 1}{ 9 } ?$

Solve the following for $$x:$$

$\frac{ 6 } { x - 6 } = \frac{ x } { 8 } - 1.$
