expand ((1-2x)^2)/x

Solution

expand

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

Solution

\frac{1}{x} - 4 + 4 x

Solution steps

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

(1 - 2 x)^{2} = 1 - 4 x + 4 x^{2}

= \frac{1 - 4 x + 4 x ^{2}}{x}

Apply the fraction rule:

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

\frac{1 - 4 x + 4 x ^{2}}{x} = \frac{1}{x} - \frac{4 x}{x} + \frac{4 x ^{2}}{x}

= \frac{1}{x} - \frac{4 x}{x} + \frac{4 x ^{2}}{x}

Cancel

\frac{4 x}{x} : 4

= \frac{1}{x} - 4 + \frac{4 x ^{2}}{x}

Cancel

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

= \frac{1}{x} - 4 + 4 x
