expand ((80-p)/2)*(p-(w+4))

expand

(\frac{80 - p}{2}) \cdot (p - (w + 4))

\frac{- p ^{2} - 80 w + 84 p + pw - 320}{2}

Solution steps

(\frac{80 - p}{2}) (p - (w + 4))

Apply rule:

(a) = a

(\frac{80 - p}{2}) = \frac{80 - p}{2}

= \frac{80 - p}{2} (p - (w + 4))

Apply the distributive law:

a (b - c) = ab - a c

\frac{80 - p}{2} (p - (w + 4)) = \frac{80 - p}{2} p - \frac{80 - p}{2} (w + 4)

= \frac{80 - p}{2} p - \frac{80 - p}{2} (w + 4)

Simplify

\frac{80 - p}{2} p - \frac{80 - p}{2} (w + 4) : \frac{- p ^{2} - 80 w + 84 p + pw - 320}{2}

= \frac{- p ^{2} - 80 w + 84 p + pw - 320}{2}

(x + 3) + i (y - 3)

(\frac{5}{6} + \frac{1}{6})^{4}

(5, - 1) y (2, - 2)

(a - 3 x + 1) (a + 3 x + 1)

\frac{( 1 - e ^{- 2 s} ) s - 26}{s ^{2} ( s ^{2} + 2 s )}
