expand (-2s^3+6s^2-17s+54)/((s^2+9)^2)

expand

\frac{- 2 s ^{3} + 6 s ^{2} - 17 s + 54}{( s ^{2} + 9 ) ^{2}}

\frac{- 2 s ^{3} + 6 s ^{2} - 17 s + 54}{s ^{4} + 18 s ^{2} + 81}

Solution steps

\frac{- 2 s ^{3} + 6 s ^{2} - 17 s + 54}{( s ^{2} + 9 ) ^{2}}

(s^{2} + 9)^{2} = s^{4} + 18 s^{2} + 81

= \frac{- 2 s ^{3} + 6 s ^{2} - 17 s + 54}{s ^{4} + 18 s ^{2} + 81}

\frac{2 ( 5 + 2 \cdot 5 ^{\frac{1}{2}} )}{5}

(\frac{1}{3} e^{x} + \frac{5}{3} e^{- 2 x}) \cdot (e^{x} - 2 y)

a (- 2, 4) b (1, 2) c (0, - 3)

5^{(n - 1)} + 2^{(n - 1)}

\frac{\partial}{\partial x} ((z) (z^{x} - 4 x y^{3} + z))
