expand (x^2)/(s*(s+x)^2)

expand

\frac{x ^{2}}{s \cdot ( s + x ) ^{2}}

\frac{x ^{2}}{s ^{3} + 2 x s ^{2} + x ^{2} s}

Solution steps

\frac{x ^{2}}{s ( s + x ) ^{2}}

(s + x)^{2} = s^{2} + 2 x s + x^{2}

= \frac{x ^{2}}{s ( x ^{2} + 2 x s + s ^{2} )}

Expand

s (s^{2} + 2 s x + x^{2}) : s^{3} + 2 x s^{2} + x^{2} s

= \frac{x ^{2}}{s ^{3} + 2 x s ^{2} + x ^{2} s}

\frac{20 ( 5 + 3 t )}{1 + 0.04 t}

\frac{( 2 a - 1 ) ( 4 a - 1 ) ^{2}}{32}

\frac{sin ( ( n - 2 ) π )}{( n - 2 ) π}

\frac{4 x + 1}{x ^{2} ( x ^{2} + x + 1 )}

\frac{4}{( s + 4 ) ^{3}}
