expand ((x-1)(x-10))/2

expand

\frac{( x - 1 ) ( x - 10 )}{2}

\frac{x ^{2}}{2} - \frac{11 x}{2} + 5

Solution steps

\frac{( x - 1 ) ( x - 10 )}{2}

Expand

(x - 1) (x - 10) : x^{2} - 11 x + 10

= \frac{x ^{2} - 11 x + 10}{2}

Apply the fraction rule:

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

\frac{x ^{2} - 11 x + 10}{2} = \frac{x ^{2}}{2} - \frac{11 x}{2} + \frac{10}{2}

= \frac{x ^{2}}{2} - \frac{11 x}{2} + \frac{10}{2}

Divide the numbers:

\frac{10}{2} = 5

= \frac{x ^{2}}{2} - \frac{11 x}{2} + 5

(4 v^{2} y^{2} + 3 y^{2}) (v d y + y d v)

\frac{( n - 2 ) ( n - 3 )}{( n + 2 ) ( n + 1 )}

e^{2 - t} u (t - 2)

\frac{1}{x ( x - 1 ) ( x + 1 )}

\frac{( n + i ) ^{2}}{n ^{2}}
