# The partial fractions of are

Hint:

### In order to integrate a rational function, it is reduced to a proper rational function. The method in which the integrand is expressed as the sum of simpler rational functions is known as decomposition into **partial fractions**. After splitting the integrand into partial fractions, it is integrated accordingly with the help of traditional integrating techniques.

**The stepwise procedure for finding the partial fraction decomposition is explained here::**

**Step 1: **While decomposing the rational expression into the partial fraction, begin with the proper rational expression.
**Step 2:** Now, factor the denominator of the rational expression into the linear factor or in the form of irreducible quadratic factors (Note: Don’t factor the denominators into the complex numbers).
**Step 3:** Write down the partial fraction for each factor obtained, with the variables in the numerators, say A and B.
**Step 4: **To find the variable values of A and B, multiply the whole equation by the denominator.
**Step 5: **Solve for the variables by substituting zero in the factor variable.
**Step 6:** Finally, substitute the values of A and B in the partial fractions.
