expand ((z-7)^2)/z

Solution

expand

\frac{( z - 7 ) ^{2}}{z}

Solution

z - 14 + \frac{49}{z}

Solution steps

\frac{( z - 7 ) ^{2}}{z}

(z - 7)^{2} = z^{2} - 14 z + 49

= \frac{z ^{2} - 14 z + 49}{z}

Apply the fraction rule:

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

\frac{z ^{2} - 14 z + 49}{z} = \frac{z ^{2}}{z} - \frac{14 z}{z} + \frac{49}{z}

= \frac{z ^{2}}{z} - \frac{14 z}{z} + \frac{49}{z}

Cancel

\frac{z ^{2}}{z} : z

= z - \frac{14 z}{z} + \frac{49}{z}

Cancel

\frac{14 z}{z} : 14

= z - 14 + \frac{49}{z}
