## Partial Fractions

Functions of $x$ that can be expressed in the form $P(x)/Q(x)$, where both $P(x)$ and $Q(x)$ are polynomials of $x$, is known as **rational fraction**. A rational fraction is known to be a **proper fraction** if $P(x)$ is less in degree power than $Q(x)$. Example of proper fraction is...
