expand ((2s-105)(4s-10945))/8

expand

\frac{( 2 s - 105 ) ( 4 s - 10945 )}{8}

s^{2} - \frac{11155 s}{4} + \frac{1149225}{8}

Solution steps

\frac{( 2 s - 105 ) ( 4 s - 10945 )}{8}

Expand

(2 s - 105) (4 s - 10945) : 8 s^{2} - 22310 s + 1149225

= \frac{8 s ^{2} - 22310 s + 1149225}{8}

Apply the fraction rule:

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

\frac{8 s ^{2} - 22310 s + 1149225}{8} = \frac{8 s ^{2}}{8} - \frac{22310 s}{8} + \frac{1149225}{8}

= \frac{8 s ^{2}}{8} - \frac{22310 s}{8} + \frac{1149225}{8}

Divide the numbers:

\frac{8}{8} = 1

= s^{2} - \frac{22310 s}{8} + \frac{1149225}{8}

Cancel

\frac{22310 s}{8} : \frac{11155 s}{4}

= s^{2} - \frac{11155 s}{4} + \frac{1149225}{8}

\frac{d x}{( a - x ) ^{3}}

p (x, y) A (- 3, - 4) B (1, 2)

\frac{d}{d x} ((z) (\frac{y}{x + y} - z))

\frac{r ( 9 - 2 r )}{( r ^{2} - 9 r - 9 )}

\frac{- 2 x ^{3} - 6 x ^{2} a - a}{( x ^{3} - a ) ^{2}}
