expand ((x-3)(-x+10))/2

expand

\frac{( x - 3 ) ( - x + 10 )}{2}

- \frac{x ^{2}}{2} + \frac{13 x}{2} - 15

Solution steps

\frac{( x - 3 ) ( - x + 10 )}{2}

Expand

(x - 3) (- x + 10) : - x^{2} + 13 x - 30

= \frac{- x ^{2} + 13 x - 30}{2}

Apply the fraction rule:

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

\frac{- x ^{2} + 13 x - 30}{2} = - \frac{x ^{2}}{2} + \frac{13 x}{2} - \frac{30}{2}

= - \frac{x ^{2}}{2} + \frac{13 x}{2} - \frac{30}{2}

Divide the numbers:

\frac{30}{2} = 15

= - \frac{x ^{2}}{2} + \frac{13 x}{2} - 15

(\frac{x ^{3}}{6} + 6 e^{x} + 5)^{2}

- 2 (3 x - 4 y = 21)

\frac{1}{( z + 9 ) ^{5}}

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

\frac{n ^{2} - 6 n - 16}{( n - 2 ) ( n - 3 )}
