expand (2(2z-5))/(45)

expand

\frac{2 ( 2 z - 5 )}{45}

\frac{4 z}{45} - \frac{2}{9}

Solution steps

\frac{2 ( 2 z - 5 )}{45}

Expand

2 (2 z - 5) : 4 z - 10

= \frac{4 z - 10}{45}

Apply the fraction rule:

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

\frac{4 z - 10}{45} = \frac{4 z}{45} - \frac{10}{45}

= \frac{4 z}{45} - \frac{10}{45}

Cancel

\frac{10}{45} : \frac{2}{9}

= \frac{4 z}{45} - \frac{2}{9}

- \frac{- s ^{2} + 4}{( s ^{2} + 4 ) ^{2}} + \frac{s}{s ^{2} + 4}

(x - a^{\frac{1}{3}})^{3}

(4 - \frac{1}{x})^{2}

\frac{720}{( 3 - 1 ) ^{7}} + sin (3 - 1)

\frac{6}{2}
