expand ((-5x+55)(11-x))/2

expand

\frac{( - 5 x + 55 ) ( 11 - x )}{2}

\frac{5 x ^{2}}{2} - 55 x + \frac{605}{2}

Solution steps

\frac{( - 5 x + 55 ) ( 11 - x )}{2}

Expand

(- 5 x + 55) (11 - x) : 5 x^{2} - 110 x + 605

= \frac{5 x ^{2} - 110 x + 605}{2}

Apply the fraction rule:

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

\frac{5 x ^{2} - 110 x + 605}{2} = \frac{5 x ^{2}}{2} - \frac{110 x}{2} + \frac{605}{2}

= \frac{5 x ^{2}}{2} - \frac{110 x}{2} + \frac{605}{2}

Divide the numbers:

\frac{110}{2} = 55

= \frac{5 x ^{2}}{2} - 55 x + \frac{605}{2}

\frac{1}{( s + 10 ) ( s ^{2} + 4 s + 10 )}

(3 + 2 i) \cdot [6 + 3 i, 0 + 0 i, 5 + 1 i, 4]

lo g_{8} (27)

\frac{s + 2}{( s + 1 ) ( s + 3 )}

\frac{( a + h ) + 8}{- 3 ( a + h ) + 5}
