simplify 1+1z^{-1}-0.2z^{-2}

Solution

simplify

1 + 1 z^{- 1} - 0.2 z^{- 2}

Solution

1 + \frac{1}{z} - \frac{1}{5 z ^{2}}

Solution steps

1 + 1 \cdot z^{- 1} - 0.2 z^{- 2}

1 \cdot z^{- 1} = \frac{1}{z}

0.2 z^{- 2} = 0.2 \cdot \frac{1}{z ^{2}}

= 1 + \frac{1}{z} - 0.2 \cdot \frac{1}{z ^{2}}

Simplify

0.2 \cdot \frac{1}{z ^{2}} : \frac{2}{10 z ^{2}}

= 1 + \frac{1}{z} - \frac{2}{10 z ^{2}}

Cancel

\frac{2}{10} : \frac{1}{5}

= 1 + \frac{1}{z} - \frac{1}{5 z ^{2}}
