expand (u(1+7s)-s^3)/(s^2(s^2+4))

expand

\frac{u ( 1 + 7 s ) - s ^{3}}{s ^{2} ( s ^{2} + 4 )}

\frac{u + 7 u s - s ^{3}}{s ^{4} + 4 s ^{2}}

Solution steps

\frac{u ( 1 + 7 s ) - s ^{3}}{s ^{2} ( s ^{2} + 4 )}

Expand

s^{2} (s^{2} + 4) : s^{4} + 4 s^{2}

= \frac{u ( 7 s + 1 ) - s ^{3}}{s ^{4} + 4 s ^{2}}

Expand

u (1 + 7 s) - s^{3} : u + 7 u s - s^{3}

= \frac{u + 7 u s - s ^{3}}{s ^{4} + 4 s ^{2}}

\frac{d ^{2}}{d x ^{2}} ((y) (\frac{9 x ^{4}}{4} - x + 3 e^{x}))

\frac{1}{( x - a ) ^{3}} - \frac{1}{( x + a ) ^{3}}

\frac{( 400 - x ) ^{2}}{100}

x^{x^{x}} (x^{x} ln (x) (ln (x) + 1) + (x^{x - 1}))

o f (o, x, y) (x^{2} + 2 y^{2} = 4)
