# Integration by Partial Fraction Decomposition applies to rational functions This technique relies on *The Fundamental Theorem of Algebra*, which states: 1. Every polynomial of degree $n$ has $n$ roots, which implies that… 2. Every polynomial of degree $n$ can be factored into a product of $n$ linear terms $\frac{A}{B} + \frac{C}{D} = \frac{AD + BC}{BD}$ https://share.goodnotes.com/s/n2JAjePFxlHdSrb8Rtbr9e ![[20250703_113200.jpg|275]]
