expand (z+19)/(z^2(z-1))

expand

\frac{z + 19}{z ^{2} ( z - 1 )}

\frac{z + 19}{z ^{3} - z ^{2}}

Solution steps

\frac{z + 19}{z ^{2} ( z - 1 )}

Expand

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

= \frac{z + 19}{z ^{3} - z ^{2}}

8 \times 15

(4, 55 + 6.79 i) (\frac{10}{10 + 5 i})

\frac{1}{2} (cos (3 x) - cos (25 x))

\frac{d x}{( 9 + x ^{2} ) ^{2}}

(s - 3 i - 3)^{3}
