展开

\frac{6 ( 7 x + 6 )}{( x + 6 ) ( x - 6 )}

\frac{42 x + 36}{x ^{2} - 36}

求解步骤

\frac{6 ( 7 x + 6 )}{( x + 6 ) ( x - 6 )}

乘开

(x + 6) (x - 6) : x^{2} - 36

= \frac{6 ( 7 x + 6 )}{x ^{2} - 36}

乘开

6 (7 x + 6) : 42 x + 36

= \frac{42 x + 36}{x ^{2} - 36}

e x p an d 2 x + 3 vx (v d x + x d v)

\frac{d}{d t} ((s (t)) (t (t - 6)^{2}))

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

e x p an d (x + y) ln (10)

e x p an d 10 (1 - e^{(- 0.5 t)})
