expand ((-x+11)(-x+10))/2

expand

\frac{( - x + 11 ) ( - x + 10 )}{2}

\frac{x ^{2}}{2} - \frac{21 x}{2} + 55

Solution steps

\frac{( - x + 11 ) ( - x + 10 )}{2}

Expand

(- x + 11) (- x + 10) : x^{2} - 21 x + 110

= \frac{x ^{2} - 21 x + 110}{2}

Apply the fraction rule:

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

\frac{x ^{2} - 21 x + 110}{2} = \frac{x ^{2}}{2} - \frac{21 x}{2} + \frac{110}{2}

= \frac{x ^{2}}{2} - \frac{21 x}{2} + \frac{110}{2}

Divide the numbers:

\frac{110}{2} = 55

= \frac{x ^{2}}{2} - \frac{21 x}{2} + 55

\frac{d}{d y} ((x) (I n (x + y + 1)))

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

\frac{4 x ^{2}}{( 3 + x ^{3} ) ^{2}}

e^{x} (1 - e^{x})

\frac{x ^{2} + 12 x - 9}{( x + 3 ) ( x - 3 )}
