展开

\frac{2 b p + 8 b - 5 a}{2 ( p - 1 ) ( p + 3 )}

\frac{2 b p + 8 b - 5 a}{2 p ^{2} + 4 p - 6}

求解步骤

\frac{2 b p + 8 b - 5 a}{2 ( p - 1 ) ( p + 3 )}

乘开

2 (p - 1) (p + 3) : 2 p^{2} + 4 p - 6

= \frac{2 b p + 8 b - 5 a}{2 p ^{2} + 4 p - 6}

e x p an d \frac{40 ( 2 - x ^{\frac{1}{5}} ) ^{3}}{3}

e x p an d ((4 - x) (4 - x^{2})) 2 y

e x p an d \frac{x ( x + 20 )}{20}

e x p an d - 4 (3) (- 72)

e x p an d sinh (a (t - b)) H (t - b)
