expand ((x-1)sqrt(x+5))/2

expand

\frac{( x - 1 ) x + 5}{2}

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

Solution steps

\frac{( x - 1 ) x + 5}{2}

Expand

(x - 1) x + 5 : x x + 5 - x + 5

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

Apply the fraction rule:

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

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

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

2 (\frac{4}{e ^{4}} + \frac{4}{e ^{16}} + \frac{4}{e ^{36}})

\frac{2 w ^{2} - 13 w + 21}{( w + 2 ) ( w - 6 )}

\frac{( 1 - u ) ^{3}}{3}

x (\frac{( 7 - x ) ^{2}}{18} - \frac{1}{2})

\frac{1}{2} + \frac{3}{44} ((5 \cdot 1.2) - \frac{( 1. 2 ^{3} )}{3})
