expand (p(60-p))/2

expand

\frac{p ( 60 - p )}{2}

- \frac{p ^{2}}{2} + 30 p

Solution steps

\frac{p ( 60 - p )}{2}

Expand

p (60 - p) : 60 p - p^{2}

= \frac{60 p - p ^{2}}{2}

Apply the fraction rule:

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

\frac{60 p - p ^{2}}{2} = \frac{60 p}{2} - \frac{p ^{2}}{2}

= \frac{60 p}{2} - \frac{p ^{2}}{2}

Divide the numbers:

\frac{60}{2} = 30

= 30 p - \frac{p ^{2}}{2}

Rewrite in standard form

= - \frac{p ^{2}}{2} + 30 p

\frac{d}{d u} ((x (u, t)) (t^{2} + 5 t))

(ln (x) - 1)^{3}

\frac{d ^{2}}{d x ^{2}} ((y) (6 x - 3))

\frac{7 s - 16}{( s - 2 ) ^{2} + 16}
