展开

\frac{3 ( 12 x + 11 )}{2}

18 x + \frac{33}{2}

求解步骤

\frac{3 ( 12 x + 11 )}{2}

乘开

3 (12 x + 11) : 36 x + 33

= \frac{36 x + 33}{2}

使用分式法则:

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

\frac{36 x + 33}{2} = \frac{36 x}{2} + \frac{33}{2}

= \frac{36 x}{2} + \frac{33}{2}

数字相除:

\frac{36}{2} = 18

= 18 x + \frac{33}{2}
