\(\frac{Y\left(z\right)}{U\left(z\right)}=\frac{\left(b+1\right)z-ab}{\left(z-a\right)\left(z-b\right)}\)

\(\frac{Y\left(z\right)}{U\left(z\right)}=\frac{z-ab}{\left(z-a\right)\left(z-b\right)}\)

\(\frac{Y\left(z\right)}{U\left(z\right)}=\frac{z-ab+1}{z-a}\)

\(\frac{Y\left(z\right)}{U\left(z\right)}=\frac{\left(a+1\right)z-b}{z-b}\)

\(\frac{Y\left(z\right)}{U\left(z\right)}=\frac{\left(b+1\right)z-ab}{z-a}\)
