expand (z^2)/((z-1)(z-0.5)(z-0.2))

expand

\frac{z ^{2}}{( z - 1 ) ( z - 0.5 ) ( z - 0.2 )}

\frac{z ^{2}}{z ^{3} - 1.7 z ^{2} + 0.8 z - 0.1}

Solution steps

\frac{z ^{2}}{( z - 1 ) ( z - 0.5 ) ( z - 0.2 )}

Expand

(z - 1) (z - 0.5) (z - 0.2) : z^{3} - 1.7 z^{2} + 0.8 z - 0.1

= \frac{z ^{2}}{z ^{3} - 1.7 z ^{2} + 0.8 z - 0.1}

\frac{3 - x}{( x - 4 ) ( x - 6 )}

\frac{- 14400 + l ^{2}}{2 ( l + 180 )}

(x - 1) (x - \frac{2}{x} = 1)

- \frac{27}{7 \cdot ( s + 3 ) ^{2}}

x y + x^{2} + 1 + (x^{2} + x) \cdot \frac{d y}{d x}
