inverse of [(z^2)/((z-1)(z-3))]

inverse

[\frac{z ^{2}}{( z - 1 ) ( z - 3 )}]

\frac{2 z + z ( z + 3 )}{z - 1}, \frac{2 z - z ( z + 3 )}{z - 1}

Solution steps

y = \frac{z ^{2}}{( z - 1 ) ( z - 3 )}

Replace

z

with

y

z = \frac{y ^{2}}{( y - 1 ) ( y - 3 )}

Solve for

y, z = \frac{y ^{2}}{( y - 1 ) ( y - 3 )}

\frac{2 z + z ( z + 3 )}{z - 1}, \frac{2 z - z ( z + 3 )}{z - 1}
