expand (k(3k+7))/2

Solution

expand

\frac{k ( 3 k + 7 )}{2}

Solution

\frac{3 k ^{2}}{2} + \frac{7 k}{2}

Solution steps

\frac{k ( 3 k + 7 )}{2}

Expand

k (3 k + 7) : 3 k^{2} + 7 k

= \frac{3 k ^{2} + 7 k}{2}

Apply the fraction rule:

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

\frac{3 k ^{2} + 7 k}{2} = \frac{3 k ^{2}}{2} + \frac{7 k}{2}

= \frac{3 k ^{2}}{2} + \frac{7 k}{2}
