解答

展开

\frac{x + 4}{( 3 x + 2 ) ( x - 8 )}

\frac{x + 4}{3 x ^{2} - 22 x - 16}

求解步骤

\frac{x + 4}{( 3 x + 2 ) ( x - 8 )}

乘开

(3 x + 2) (x - 8) : 3 x^{2} - 22 x - 16

= \frac{x + 4}{3 x ^{2} - 22 x - 16}

e x p an d \frac{( 3 x + 4 ) ( x - 9 )}{( x - 2 ) ( x + 2 )}

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

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

e x p an d \frac{( e ^{- s} + s ^{2} + s + 10 )}{( s + 4 ) ( s - 2 ) ( s - 1 )}

e x p an d \frac{s ^{2} + 9 s + 10}{( s + 1 ) ( s ^{2} + 5 s + 6 )}
