Question

What should be checked before beginning partial-fraction decomposition?

Options

• Whether all factors are irreducible quadratic factors.

• Whether the rational function is proper or improper.

• Whether the constant of integration is zero.

• Whether \[\mathrm{A}=\mathrm{B}=\mathrm{C}\].

Answer 1

The first step is to check whether the rational function is proper or improper. An improper rational function requires long division first.
