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

expand

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

x^{2} - k x + \frac{k ^{2}}{4}

Solution steps

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

(2 x - k)^{2} = 4 x^{2} - 4 k x + k^{2}

= \frac{4 x ^{2} - 4 k x + k ^{2}}{4}

Apply the fraction rule:

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

\frac{4 x ^{2} - 4 k x + k ^{2}}{4} = \frac{4 x ^{2}}{4} - \frac{4 k x}{4} + \frac{k ^{2}}{4}

= \frac{4 x ^{2}}{4} - \frac{4 k x}{4} + \frac{k ^{2}}{4}

Divide the numbers:

\frac{4}{4} = 1

= x^{2} - k x + \frac{k ^{2}}{4}

t e^{x t} (e^{jb t} + e^{- jb t})

\frac{( x + 2 ) ^{2}}{20 ( y - 5 )}

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