\frac{15 a}{s ( 3 s + 8 )}

\frac{15 a}{3 s ^{2} + 8 s}

求解步骤

\frac{15 a}{s ( 3 s + 8 )}

乘开

s (3 s + 8) : 3 s^{2} + 8 s

= \frac{15 a}{3 s ^{2} + 8 s}

e x p an d (x^{3} y^{2} - y) d x + (x^{2} y^{2} - x) d y

e x p an d x (1 + x ln (x y - 5))

e x p an d \frac{5}{6} - 2

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

e x p an d \frac{( n ! + 1 ) ^{3}}{( 8 n + 1 ) !}
