simplify (z-1)*(z-4/5)

Solution

simplify

(z - 1) \cdot (z - \frac{4}{5})

Solution

\frac{( z - 1 ) ( 5 z - 4 )}{5}

Solution steps

(z - 1) (z - \frac{4}{5})

Simplify

z - \frac{4}{5} : \frac{5 z - 4}{5}

= (z - 1) \frac{5 z - 4}{5}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{( z - 1 ) ( 5 z - 4 )}{5}
