I have an equation of the following form:
[tex] \frac {dz}{z^2 - z} [/tex]
Of course, I factor this into:
[tex] (z + \sqrt{z})(z - \sqrt{z}) [/tex]
then,
[tex]
\frac{A}{z + \sqrt{z}} + \frac{B}{z - \sqrt{z}}
[/tex]
of course cross multiply the denominators to get:
[tex] A(z - \sqrt{z}) + B(z + \sqrt{z}) = 1 [/tex]
But then what? do I equate the z terms to 1 and the square root terms to 0?
[tex] \frac {dz}{z^2 - z} [/tex]
Of course, I factor this into:
[tex] (z + \sqrt{z})(z - \sqrt{z}) [/tex]
then,
[tex]
\frac{A}{z + \sqrt{z}} + \frac{B}{z - \sqrt{z}}
[/tex]
of course cross multiply the denominators to get:
