expand (n(197-3n))/2

expand

\frac{n ( 197 - 3 n )}{2}

\frac{197 n}{2} - \frac{3 n ^{2}}{2}

Solution steps

\frac{n ( 197 - 3 n )}{2}

Expand

n (197 - 3 n) : 197 n - 3 n^{2}

= \frac{197 n - 3 n ^{2}}{2}

Apply the fraction rule:

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

\frac{197 n - 3 n ^{2}}{2} = \frac{197 n}{2} - \frac{3 n ^{2}}{2}

= \frac{197 n}{2} - \frac{3 n ^{2}}{2}

e^{t} (t e^{- t} + 1)

(x - 3 y)^{6}

\frac{d}{d x} ((2 x - y)^{4} - y^{3} - 8)

t^{3} \cdot t^{4}
