$(z^{4} - 3 z^{3} + 2 z^{2} - 4 z + 4) {(z - 1)}^{- 1}$

Step 1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$(z^{4} - 3 z^{3} + 2 z^{2} - 4 z + 4) \frac{1}{z - 1}$

Step 2

Multiply $z^{4} - 3 z^{3} + 2 z^{2} - 4 z + 4$ by $\frac{1}{z - 1}$ .

$\frac{z^{4} - 3 z^{3} + 2 z^{2} - 4 z + 4}{z - 1}$
