expand (k(5k-1))/2

Solution

expand

\frac{k ( 5 k - 1 )}{2}

Solution

\frac{5 k ^{2}}{2} - \frac{k}{2}

Solution steps

\frac{k ( 5 k - 1 )}{2}

Expand

k (5 k - 1) : 5 k^{2} - k

= \frac{5 k ^{2} - k}{2}

Apply the fraction rule:

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

\frac{5 k ^{2} - k}{2} = \frac{5 k ^{2}}{2} - \frac{k}{2}

= \frac{5 k ^{2}}{2} - \frac{k}{2}
