expand 1/(z(z-1)(z-2))

expand

\frac{1}{z ( z - 1 ) ( z - 2 )}

\frac{1}{z ^{3} - 3 z ^{2} + 2 z}

Solution steps

\frac{1}{z ( z - 1 ) ( z - 2 )}

Expand

z (z - 1) (z - 2) : z^{3} - 3 z^{2} + 2 z

= \frac{1}{z ^{3} - 3 z ^{2} + 2 z}

\frac{\partial}{\partial x} ((z) (x^{2} e^{y} - yz e^{x}))

\frac{( 3 x ^{2} - 1 )}{( 3 x ^{2} + 1 ) ^{2}}

\frac{( 2 + x ) ^{10}}{1024}

(sin (t) - e^{3 t}) u (t - π)

\frac{( n ^{2} + 2 n + 3 )}{( n + 1 ) ^{2}}
