- \frac{x ( x + 1 ) ( x + 10 )}{x + 5}

- \frac{x ^{3} + 11 x ^{2} + 10 x}{x + 5}

求解步骤

- \frac{x ( x + 1 ) ( x + 10 )}{x + 5}

乘开

x (x + 1) (x + 10) : x^{3} + 11 x^{2} + 10 x

= - \frac{x ^{3} + 11 x ^{2} + 10 x}{x + 5}

e x p an d 3 + 3 (x + \frac{π}{4})

e x p an d (r + d r)^{3}

e x p an d 2 3 + 5 + 13 + 48 = a + b

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

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