expand (13x(2x+1))/2

Solution

expand

\frac{13 x ( 2 x + 1 )}{2}

Solution

13 x^{2} + \frac{13 x}{2}

Solution steps

\frac{13 x ( 2 x + 1 )}{2}

Expand

13 x (2 x + 1) : 26 x^{2} + 13 x

= \frac{26 x ^{2} + 13 x}{2}

Apply the fraction rule:

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

\frac{26 x ^{2} + 13 x}{2} = \frac{26 x ^{2}}{2} + \frac{13 x}{2}

= \frac{26 x ^{2}}{2} + \frac{13 x}{2}

Divide the numbers:

\frac{26}{2} = 13

= 13 x^{2} + \frac{13 x}{2}
