expand (x(381-5x))/2

expand

\frac{x ( 381 - 5 x )}{2}

- \frac{5 x ^{2}}{2} + \frac{381 x}{2}

Solution steps

\frac{x ( 381 - 5 x )}{2}

Expand

x (381 - 5 x) : 381 x - 5 x^{2}

= \frac{381 x - 5 x ^{2}}{2}

Apply the fraction rule:

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

\frac{381 x - 5 x ^{2}}{2} = \frac{381 x}{2} - \frac{5 x ^{2}}{2}

= \frac{381 x}{2} - \frac{5 x ^{2}}{2}

Rewrite in standard form

= - \frac{5 x ^{2}}{2} + \frac{381 x}{2}

(t π - t^{2})^{2}

- \frac{10 x}{( x - 3 ) ^{2}}

(4 x + 2) (6 x - 12)^{\circ}

4 a 2 + a

5 \cdot (72 = 23 x - 12 y)
