expand ((a-2)^2)/a

Solution

expand

\frac{( a - 2 ) ^{2}}{a}

Solution

a - 4 + \frac{4}{a}

Solution steps

\frac{( a - 2 ) ^{2}}{a}

(a - 2)^{2} = a^{2} - 4 a + 4

= \frac{a ^{2} - 4 a + 4}{a}

Apply the fraction rule:

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

\frac{a ^{2} - 4 a + 4}{a} = \frac{a ^{2}}{a} - \frac{4 a}{a} + \frac{4}{a}

= \frac{a ^{2}}{a} - \frac{4 a}{a} + \frac{4}{a}

Cancel

\frac{a ^{2}}{a} : a

= a - \frac{4 a}{a} + \frac{4}{a}

Cancel

\frac{4 a}{a} : 4

= a - 4 + \frac{4}{a}
