expand ((x-9)^2)/9

Solution

expand

\frac{( x - 9 ) ^{2}}{9}

Solution

\frac{x ^{2}}{9} - 2 x + 9

Solution steps

\frac{( x - 9 ) ^{2}}{9}

(x - 9)^{2} = x^{2} - 18 x + 81

= \frac{x ^{2} - 18 x + 81}{9}

Apply the fraction rule:

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

\frac{x ^{2} - 18 x + 81}{9} = \frac{x ^{2}}{9} - \frac{18 x}{9} + \frac{81}{9}

= \frac{x ^{2}}{9} - \frac{18 x}{9} + \frac{81}{9}

Divide the numbers:

\frac{18}{9} = 2

= \frac{x ^{2}}{9} - 2 x + \frac{81}{9}

Divide the numbers:

\frac{81}{9} = 9

= \frac{x ^{2}}{9} - 2 x + 9
