expand ((15+x)^2)/4

expand

\frac{( 15 + x ) ^{2}}{4}

\frac{x ^{2}}{4} + \frac{15 x}{2} + \frac{225}{4}

Solution steps

\frac{( 15 + x ) ^{2}}{4}

(15 + x)^{2} = 225 + 30 x + x^{2}

= \frac{225 + 30 x + x ^{2}}{4}

Apply the fraction rule:

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

\frac{225 + 30 x + x ^{2}}{4} = \frac{225}{4} + \frac{30 x}{4} + \frac{x ^{2}}{4}

= \frac{225}{4} + \frac{30 x}{4} + \frac{x ^{2}}{4}

Cancel

\frac{30 x}{4} : \frac{15 x}{2}

= \frac{225}{4} + \frac{15 x}{2} + \frac{x ^{2}}{4}

Rewrite in standard form

= \frac{x ^{2}}{4} + \frac{15 x}{2} + \frac{225}{4}

\frac{f ( t - 1 )}{t}

(2 ln (2) + 4) (x - 1)

\frac{18 s}{( s ^{2} + 9 ) ^{2}}

\frac{3 h ^{2} - 18 h}{- 3 h ( h + 6 )}
