expand ((21x-2)^2)/(340)

expand

\frac{( 21 x - 2 ) ^{2}}{340}

\frac{441 x ^{2}}{340} - \frac{21 x}{85} + \frac{1}{85}

Solution steps

\frac{( 21 x - 2 ) ^{2}}{340}

(21 x - 2)^{2} = 441 x^{2} - 84 x + 4

= \frac{441 x ^{2} - 84 x + 4}{340}

Apply the fraction rule:

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

\frac{441 x ^{2} - 84 x + 4}{340} = \frac{441 x ^{2}}{340} - \frac{84 x}{340} + \frac{4}{340}

= \frac{441 x ^{2}}{340} - \frac{84 x}{340} + \frac{4}{340}

Cancel

\frac{84 x}{340} : \frac{21 x}{85}

= \frac{441 x ^{2}}{340} - \frac{21 x}{85} + \frac{4}{340}

Cancel

\frac{4}{340} : \frac{1}{85}

= \frac{441 x ^{2}}{340} - \frac{21 x}{85} + \frac{1}{85}

\frac{2 s - 4}{( s - 1 ) ( s ^{2} + 5 x + 6 )}

\frac{8 + 4 s ^{2}}{s ^{s} ( s ^{2} - 4 )}

\frac{5 t ( 3 t ^{2} + 25 )}{8 ( t ^{2} + 5 ) ^{2}}

\frac{2}{( 2 x - k ) ^{2}}

\frac{( x d x )}{( x + 1 ) ^{8}}
