Write an informal explanation of partial fraction decomposition.

Step 1

Partial-fraction decomposition is the process of starting with the simplified answer and taking it back apart, of "decomposing" the final expression into its initial polynomial fractions.

For example:

Step 2

To decompose a fraction, you first factor the denominator. Let's work backwards from the example above. The denominator is *x*^{2} + *x*, which factors as *x*(*x* + 1).

Step 3

Then you write the fractions with one of the factors for each of the denominators. Of course, you don't know w...
