expand ((1-st)/2)K

Solution

expand

(\frac{1 - s t}{2}) K

Solution

\frac{K}{2} - \frac{s t K}{2}

Solution steps

(\frac{1 - s t}{2}) K

Remove parentheses:

(a) = a

= \frac{1 - s t}{2} K

Multiply fractions:

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

= \frac{( 1 - s t ) K}{2}

Expand

(1 - s t) K : K - s t K

= \frac{K - s t K}{2}

Apply the fraction rule:

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

\frac{K - s t K}{2} = \frac{K}{2} - \frac{s t K}{2}

= \frac{K}{2} - \frac{s t K}{2}
