# How do I decompose the rational expression #(x-3)/(x^3+3x)# into partial fractions?

The answer is

Perform the decomposition into partial fractions after factorising the denominator

The denominators are the same, compare the numerators

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
