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

expand

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

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

Solution steps

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

(z - 1)^{2} = z^{2} - 2 z + 1

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

\frac{2 x ^{3} - 4 x - 8}{( x ^{2} - x ) ( x ^{2} + 4 )}

\frac{1}{r ( r + 2 )}

x (272 - \frac{8 x}{7})

(5 + x) x^{4} e^{9 x} + 5

(2 e^{2 t} cos (t) + 4 e^{2 t} sin (t))^{2}
