## Homework Statement

Use partial fractions to rewrite:

(2z)/(z^2+3)

## Homework Equations

none

## The Attempt at a Solution

I did this:

(2z)/(z^2+3) = (Az+B)/(z^2+3)

2z = Az +B

A = 2, B = 0......problem is that it just recreates the original

Here is their example in the book:

1/(z^2+1) = 1/(2i(z-i)) - 1/(2i(z+i))

I don't understand how they came to their conclusion in their example.

Any help understanding their example or my question is appreciated.
