expand (n(11-n))/2

Solution

expand

\frac{n ( 11 - n )}{2}

Solution

\frac{11 n}{2} - \frac{n ^{2}}{2}

Solution steps

\frac{n ( 11 - n )}{2}

Expand

n (11 - n) : 11 n - n^{2}

= \frac{11 n - n ^{2}}{2}

Apply the fraction rule:

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

\frac{11 n - n ^{2}}{2} = \frac{11 n}{2} - \frac{n ^{2}}{2}

= \frac{11 n}{2} - \frac{n ^{2}}{2}
