展开

\frac{s}{( ( x ^{2} + 9 ) \cdot ( x ^{2} + 4 ) )}

\frac{s}{x ^{4} + 13 x ^{2} + 36}

求解步骤

\frac{s}{( x ^{2} + 9 ) ( x ^{2} + 4 )}

乘开

(x^{2} + 9) (x^{2} + 4) : x^{4} + 13 x^{2} + 36

= \frac{s}{x ^{4} + 13 x ^{2} + 36}

e x p an d (1 + 2 x)^{(\frac{1}{2})}

e x p an d \frac{1}{2 ( x + 4 )}

e x p an d p^{1} (\frac{5}{4}, - \frac{7}{2})

e x p an d (83) 25 (- 3 x) 3

e x p an d (1 - e^{- 0.01 x})^{5}
