\frac{3}{2 S ( S + 2 )}

\frac{3}{2 S ^{2} + 4 S}

求解步骤

\frac{3}{2 S ( S + 2 )}

乘开

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

= \frac{3}{2 S ^{2} + 4 S}

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

e x p an d \frac{x + 4}{2 + x - 6} + \frac{x - 3}{2 + 7 x + 12}

e x p an d (x + \frac{4}{3})^{2}

e x p an d (3 x - 9 x^{2} - 6 x + 3) (\frac{1}{x})

e x p an d (c = \frac{- y}{x} + x^{2}) x
