\frac{1}{x ( x + 5 )}

\frac{1}{x ^{2} + 5 x}

解答ステップ

\frac{1}{x ( x + 5 )}

拡張

x (x + 5) : x^{2} + 5 x

= \frac{1}{x ^{2} + 5 x}

e x p an d \frac{- a ( b - 2 a ) + 3 c ( - b - 2 a )}{a ( b - 2 a ) + 3 c ( b - 2 a )}

e x p an d (e^{2 t} + e^{- t})^{2}

\frac{d ^{2}}{d x ^{2}} ((z (x, y)) (x^{2} y^{2} - y^{3} + 3 x^{4} + 5))

e x p an d 3 (7 - 6)

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