expand (x(x+4))/2

Solution

expand

\frac{x ( x + 4 )}{2}

Solution

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

Solution steps

\frac{x ( x + 4 )}{2}

Expand

x (x + 4) : x^{2} + 4 x

= \frac{x ^{2} + 4 x}{2}

Apply the fraction rule:

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

\frac{x ^{2} + 4 x}{2} = \frac{x ^{2}}{2} + \frac{4 x}{2}

= \frac{x ^{2}}{2} + \frac{4 x}{2}

Divide the numbers:

\frac{4}{2} = 2

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