expand-r/8 (2s-8)

Solution

expand

- \frac{r}{8} (2 s - 8)

Solution

- \frac{rs}{4} + r

Solution steps

- \frac{r}{8} (2 s - 8)

Apply the distributive law:

a (b - c) = ab - a c

- \frac{r}{8} (2 s - 8) = - \frac{r}{8} \cdot 2 s - (- \frac{r}{8}) \cdot 8

= - \frac{r}{8} \cdot 2 s - (- \frac{r}{8}) \cdot 8

Simplify

- \frac{r}{8} \cdot 2 s - (- \frac{r}{8}) \cdot 8 : - \frac{rs}{4} + r

= - \frac{rs}{4} + r
