expand (n(1+n))/2

Solution

expand

\frac{n ( 1 + n )}{2}

Solution

\frac{n}{2} + \frac{n ^{2}}{2}

Solution steps

\frac{n ( 1 + n )}{2}

Expand

n (1 + n) : n + n^{2}

= \frac{n + n ^{2}}{2}

Apply the fraction rule:

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

\frac{n + n ^{2}}{2} = \frac{n}{2} + \frac{n ^{2}}{2}

= \frac{n}{2} + \frac{n ^{2}}{2}
