expand (x(40-3x))/(400)

expand

\frac{x ( 40 - 3 x )}{400}

- \frac{3 x ^{2}}{400} + \frac{x}{10}

Solution steps

\frac{x ( 40 - 3 x )}{400}

Expand

x (40 - 3 x) : 40 x - 3 x^{2}

= \frac{40 x - 3 x ^{2}}{400}

Apply the fraction rule:

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

\frac{40 x - 3 x ^{2}}{400} = \frac{40 x}{400} - \frac{3 x ^{2}}{400}

= \frac{40 x}{400} - \frac{3 x ^{2}}{400}

Cancel

\frac{40 x}{400} : \frac{x}{10}

= \frac{x}{10} - \frac{3 x ^{2}}{400}

Rewrite in standard form

= - \frac{3 x ^{2}}{400} + \frac{x}{10}

2 (3 x - 8 y = - 1, 3) - 2 (5 y - 2 x = - 19)

2 (ln (3) + 1)

(x - 9) (4 x - 8 (= 0))

\frac{1}{( x + 8 ) ^{3}}

\frac{( y - 1 ) ^{2}}{4}
