expand (v(v-1))/2-e

Solution

expand

\frac{v ( v - 1 )}{2} - e

Solution

\frac{v ^{2}}{2} - \frac{v}{2} - e

Solution steps

\frac{v ( v - 1 )}{2} - e

Expand

v (v - 1) : v^{2} - v

= \frac{v ^{2} - v}{2} - e

Apply the fraction rule:

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

\frac{v ^{2} - v}{2} = \frac{v ^{2}}{2} - \frac{v}{2}

= \frac{v ^{2}}{2} - \frac{v}{2} - e
