expand ((-x+11)(x-3))/2

Solution

expand

\frac{( - x + 11 ) ( x - 3 )}{2}

Solution

- \frac{x ^{2}}{2} + 7 x - \frac{33}{2}

Solution steps

\frac{( - x + 11 ) ( x - 3 )}{2}

Expand

(- x + 11) (x - 3) : - x^{2} + 14 x - 33

= \frac{- x ^{2} + 14 x - 33}{2}

Apply the fraction rule:

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

\frac{- x ^{2} + 14 x - 33}{2} = - \frac{x ^{2}}{2} + \frac{14 x}{2} - \frac{33}{2}

= - \frac{x ^{2}}{2} + \frac{14 x}{2} - \frac{33}{2}

Divide the numbers:

\frac{14}{2} = 7

= - \frac{x ^{2}}{2} + 7 x - \frac{33}{2}
