expand ((3y-1)(3-y))/(25)

expand

\frac{( 3 y - 1 ) ( 3 - y )}{25}

- \frac{3 y ^{2}}{25} + \frac{2 y}{5} - \frac{3}{25}

Solution steps

\frac{( 3 y - 1 ) ( 3 - y )}{25}

Expand

(3 y - 1) (3 - y) : - 3 y^{2} + 10 y - 3

= \frac{- 3 y ^{2} + 10 y - 3}{25}

Apply the fraction rule:

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

\frac{- 3 y ^{2} + 10 y - 3}{25} = - \frac{3 y ^{2}}{25} + \frac{10 y}{25} - \frac{3}{25}

= - \frac{3 y ^{2}}{25} + \frac{10 y}{25} - \frac{3}{25}

Cancel

\frac{10 y}{25} : \frac{2 y}{5}

= - \frac{3 y ^{2}}{25} + \frac{2 y}{5} - \frac{3}{25}

\frac{( e ^{2 x} - 1 ) ^{2}}{e ^{x}}

\frac{9}{3 - 6}

π (0.5 x + 0.4 0.5 x + 5 + 5.04)

\frac{1}{( x - 1 ) ( x + 6 )}

\frac{4 - x}{( x - 3 ) ^{2}}
