Identities and choosing a method

Flowchart showing how to choose a partial fraction form by checking whether a fraction is proper, whether factors are distinct or repeated, and when to add a polynomial part

Algebraic methods often turn one expression into another form that is easier to use. A key idea is an identity, written with ≡\equiv≡, which is true for every allowed value of xxx, so you can compare coefficients or substitute convenient values.
