expand ((12+a)13)/2

Solution

expand

\frac{( 12 + a ) 13}{2}

Solution

78 + \frac{13 a}{2}

Solution steps

\frac{( 12 + a ) \cdot 13}{2}

Expand

(12 + a) \cdot 13 : 156 + 13 a

= \frac{156 + 13 a}{2}

Apply the fraction rule:

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

\frac{156 + 13 a}{2} = \frac{156}{2} + \frac{13 a}{2}

= \frac{156}{2} + \frac{13 a}{2}

Divide the numbers:

\frac{156}{2} = 78

= 78 + \frac{13 a}{2}
