expand ((-9+m)^2)/9

expand

\frac{( - 9 + m ) ^{2}}{9}

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

Solution steps

\frac{( - 9 + m ) ^{2}}{9}

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

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

Apply the fraction rule:

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

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

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

Divide the numbers:

\frac{81}{9} = 9

= 9 - \frac{18 m}{9} + \frac{m ^{2}}{9}

Divide the numbers:

\frac{18}{9} = 2

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

- \frac{3 ( - 6 x + 5 )}{4 ( 14 + 5 x - 3 x ^{2} ) ^{\frac{7}{4}}}

I (R + (2 π F L - \frac{1}{2 π FC}))

\frac{- m + 3}{3 ( - m + 9 )}

(4 x + 2 \circ 6 x) (- 3)

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