What is a Partial Fraction Decomposition?

Let $ R (x) = \dfrac { P (x)} { Q (x)}$ be a rational function, where $ P (x)$ and $ Q (x)$ are expressible as polynomial functions.

Let $ Q (x)$ be expressible as:$ Q (x) = \displaystyle \prod_{k \mathop = 1}^n {q_k} (x)$ where the $ {q_k} (x)$ are themselves polynomial functions of degree at least $1$.

Let $ R (x)$ be expressible as:$ R (x) = r (x) \displaystyle \sum_{k \mathop = 0}^n \dfrac { {p_k} (x)} { {q_k} (x)}$ where:

$ r (x)$ is a polynomial function which may or may not be the null polynomial, or be of degree 0 (that is, a constant) each of the ${p_k} (x)$ are polynomial functions the degree of $ {p_k} (x)$ is strictly less than the degree of $ {q_k} (x)$ for all $k$.

Then $ r (x) \displaystyle \sum_{k \mathop = 0}^n \dfrac { {p_k} (x)} { {q_k} (x)}$ is a partial fractions expansion of $ R (x)$.

In simple words, Partial fraction decomposition is defined as the process of expressing an algebraic fraction as the sum of two or more algebraic fractions.

The partial fraction decomposition or partial fraction expansion of a rational function is an operation that consists of expressing the fraction as a sum of a polynomial and one or several fractions with a simpler denominator.

So, the partial fraction decomposition process offers simpler fractions for complex ones.

For this, we need first to decompose the denominator of the fraction. 

After this, you have to write the fractions with one of the factors for each denominator. As the numerators are unknown, we have to assign variables (any capital letters) for these unknown values. The result is an expression that can be more easily integrated and nondifferentiated.

Methods in Partial Fraction Decomposition

These partial fractions can be solved using various methods, such as Lagrange interpolation and residues. The Lagrange interpolation formula is a method to find a polynomial that takes on certain values at arbitrary points.

Explore these books on Alegbra to learn more about these.

But the smart and newer method to solve these is by using partial fraction calculators.

Partial Fraction Decomposition Calculator

A partial fraction calculator is an online tool that makes calculations very simple and exciting. This calculator can decompose any given rational fraction and can generate equivalent sums of fractions whose denominators cannot be reduced. It can, too, determine asymptotes and evaluate integrals.

How does it work?

This calculator works based on some steps for finding the partial fraction decomposition.

Step 1:- Enter the numerator

Say,  $x+7$

Step 2:- Enter the denominator

Eg:- $x^2+3x+2$

Step 3:- Click 'calculate'.

After following these steps you will get the solution to your problem. You can also note the steps of the solution and make out how it's done. 

By looking into these steps you might have figured out how quick this process is. 

However, do not ignore the fact that this calculator has a lot to do with it.
