expand-(n(-p+1-np))/(p(-p+1))

expand

- \frac{n ( - p + 1 - n p )}{p ( - p + 1 )}

- \frac{- n p + n - n ^{2} p}{- p ^{2} + p}

Solution steps

- \frac{n ( - p + 1 - n p )}{p ( - p + 1 )}

Expand

p (- p + 1) : - p^{2} + p

= - \frac{n ( - p - n p + 1 )}{- p ^{2} + p}

Expand

n (- p + 1 - n p) : - n p + n - n^{2} p

= - \frac{- n p - n ^{2} p + n}{- p ^{2} + p}

- 2 (100)^{2} + 400 (100) - 2000

2 (3 x + 2) (2 x + 3) - (3 x +, 1) (4 x + 3)

\frac{sin ^{2} ( x )}{( cos ( x ) + 1 ) ^{2}}

sin (x (π - \frac{π}{k}))

\frac{2 ( - 3 cos ( \frac{πn}{3} ) + 3 )}{π ^{2} n ^{2}}
