expand-(((4(2x-b)))/((b^2)))

expand

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

- \frac{8 x}{b ^{2}} + \frac{4}{b}

Solution steps

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

Remove parentheses:

(a) = a

= - \frac{4 ( 2 x - b )}{b ^{2}}

Expand

4 (2 x - b) : 8 x - 4 b

= - \frac{8 x - 4 b}{b ^{2}}

Apply the fraction rule:

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

\frac{8 x - 4 b}{b ^{2}} = - (\frac{8 x}{b ^{2}}) - (- \frac{4 b}{b ^{2}})

= - (\frac{8 x}{b ^{2}}) - (- \frac{4 b}{b ^{2}})

Remove parentheses:

(a) = a, - (- a) = a

= - \frac{8 x}{b ^{2}} + \frac{4 b}{b ^{2}}

Cancel

\frac{4 b}{b ^{2}} : \frac{4}{b}

= - \frac{8 x}{b ^{2}} + \frac{4}{b}

\frac{2}{( s - 3 ) ^{3}}

\frac{3 s - 1}{s ( s + 1 )}

\frac{1}{( x ^{2} + 9 ) ^{2}}

\frac{( 63 - 32 2 ) π}{4}

\frac{x - y}{x ( x + y ) ^{2}}
