expand (x(x-10))/2

Solution

expand

\frac{x ( x - 10 )}{2}

Solution

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

Solution steps

\frac{x ( x - 10 )}{2}

Expand

x (x - 10) : x^{2} - 10 x

= \frac{x ^{2} - 10 x}{2}

Apply the fraction rule:

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

\frac{x ^{2} - 10 x}{2} = \frac{x ^{2}}{2} - \frac{10 x}{2}

= \frac{x ^{2}}{2} - \frac{10 x}{2}

Divide the numbers:

\frac{10}{2} = 5

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