解答

展开

\frac{8 ( - x + 51 )}{17}

- \frac{8 x}{17} + 24

求解步骤

\frac{8 ( - x + 51 )}{17}

乘开

8 (- x + 51) : - 8 x + 408

= \frac{- 8 x + 408}{17}

使用分式法则:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{- 8 x + 408}{17} = - \frac{8 x}{17} + \frac{408}{17}

= - \frac{8 x}{17} + \frac{408}{17}

数字相除:

\frac{408}{17} = 24

= - \frac{8 x}{17} + 24

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

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

e x p an d (- 5 x - 3) (2 x + 1)^{''}

e x p an d 7 + \frac{1}{5}

e x p an d 5 a^{6 - 1}
