\frac{12}{x ( x ^{2} + 6 )}

\frac{12}{x ^{3} + 6 x}

求解步骤

\frac{12}{x ( x ^{2} + 6 )}

乘开

x (x^{2} + 6) : x^{3} + 6 x

= \frac{12}{x ^{3} + 6 x}

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

e x p an d (- 5, - 8) Y (- 1, 4)

e x p an d (2 a + b)^{2} + (2 c + d)^{2} + (2 e + f)^{2}

e x p an d (- 1 + \frac{x}{y})^{3}

s im pl i f y (1 + \frac{x}{2}) (2 - 3 x)^{6}
