expand ((15-3x)^2)/(25)

expand

\frac{( 15 - 3 x ) ^{2}}{25}

\frac{9 x ^{2}}{25} - \frac{18 x}{5} + 9

Solution steps

\frac{( 15 - 3 x ) ^{2}}{25}

(15 - 3 x)^{2} = 225 - 90 x + 9 x^{2}

= \frac{225 - 90 x + 9 x ^{2}}{25}

Apply the fraction rule:

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

\frac{225 - 90 x + 9 x ^{2}}{25} = \frac{225}{25} - \frac{90 x}{25} + \frac{9 x ^{2}}{25}

= \frac{225}{25} - \frac{90 x}{25} + \frac{9 x ^{2}}{25}

Divide the numbers:

\frac{225}{25} = 9

= 9 - \frac{90 x}{25} + \frac{9 x ^{2}}{25}

Cancel

\frac{90 x}{25} : \frac{18 x}{5}

= 9 - \frac{18 x}{5} + \frac{9 x ^{2}}{25}

Rewrite in standard form

= \frac{9 x ^{2}}{25} - \frac{18 x}{5} + 9

\frac{d}{d y} ((x) (4 x - 0.5 y^{2} - 0.5 x^{2}))

\frac{( e ^{3 t} - 1 ) ^{2}}{3 e ^{- 5 t}}

e^{x} (1 + 8 x)

\frac{8 k ( 2 - k )}{15 - 2 k}

- (\frac{2 x ^{2} + 5 x + 9}{( x ^{2} + 7 ) ( x - 1 )})
