Here are the basic Partial Fraction Rules when for decomposing fractions. Basic Partial Fraction Decomposition Rules If an integral is improper (the degree of the numerator is greater than or equal to the degree of the denominator), use polynomial long division to get a term that’s not a rational function, and then decompose the remaining terms we’ll show an example below. We’ll see that when we do this, we’ll usually end up with integrating logarithmic functions or integrating inverse trigonometric functions. The basic idea is to factor the denominator (if it isn’t already factored) of the complicated factor, and then break it up into different fractions with denominators of those factors. In more advanced cases, you may need to use Completing the Square or another method to get the rational in the right form). (Note that Partial Fraction Decomposition may really only be used with rationals with denominators that factor well. Note that Integration by Partial Fractions is used when U-Substitution Integration doesn’t work easily a rule of thumb is to try U-sub first!

You may have learned how to use this technique in your Algebra class, and it’s quite useful in Calculus! Basically, we are breaking up one “complicated” fraction into several different “less complicated” fractions. Integration by Partial Fraction Decomposition is a procedure where we can “decompose” a proper rational function into simpler rational functions that are more easily integrated.
