# Miscellaneous Equations

If you look at the following equation, you would not say it is a quadratic equation. However, by simplifying it, we obtain a quadratic equation and we therefore apply methods for solving quadratic equations when trying to solving it.

Example

An equation containing rational expressions

Solution

The least common denominator (LCD) for x, x - 2, and 8 is 8x(x - 2).

 Multiply each side by the LCD. 8x - 16 + 24x = 5x2 - 10x 32x - 16 = 5x2 - 10x -5x2 + 42x - 16 = 0 5x2 - 42x + 16 = 0 Multiply each side by -1 for easier factoring. (5x - 2)(x - 8) = 0 Factor. 5x - 2 = 0 or x - 8 = 0 x or x = 8

Check these values in the original equation. The solution set is .
