There are two kinds of asymptotes. The **vertical** ones are when the part under the fraction bar approaches zero.

#### Explanation:

You can factor

Now you can expect asymptotes at

For the **horizontal** asymptote we make

If we cross out the

As

graph{(-7x+5)/(x^2+8x-20) [-32.48, 32.47, -16.23, 16.26]}
