expand ((5-x)^2)/2

expand

\frac{( 5 - x ) ^{2}}{2}

\frac{x ^{2}}{2} - 5 x + \frac{25}{2}

Solution steps

\frac{( 5 - x ) ^{2}}{2}

(5 - x)^{2} = 25 - 10 x + x^{2}

= \frac{25 - 10 x + x ^{2}}{2}

Apply the fraction rule:

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

\frac{25 - 10 x + x ^{2}}{2} = \frac{25}{2} - \frac{10 x}{2} + \frac{x ^{2}}{2}

= \frac{25}{2} - \frac{10 x}{2} + \frac{x ^{2}}{2}

Divide the numbers:

\frac{10}{2} = 5

= \frac{25}{2} - 5 x + \frac{x ^{2}}{2}

Rewrite in standard form

= \frac{x ^{2}}{2} - 5 x + \frac{25}{2}

n (\frac{ln ( n + 1 )}{ln ( n )} - 1)

\frac{( 2 x + 5 ) ^{2}}{4}

4!

6!

(4 + \frac{1}{8} x)^{6}
