化简 (4y+1/6)(4y-1/6)

解答

化简

(4 y + \frac{1}{6}) (4 y - \frac{1}{6})

\frac{( 24 y + 1 ) ( 24 y - 1 )}{36}

求解步骤

(4 y + \frac{1}{6}) (4 y - \frac{1}{6})

合并

4 y + \frac{1}{6} : \frac{24 y + 1}{6}

= \frac{24 y + 1}{6} (4 y - \frac{1}{6})

使用分式法则:

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

= \frac{( 24 y + 1 ) ( 4 y - \frac{1}{6} )}{6}

化简

(24 y + 1) (4 y - \frac{1}{6}) : \frac{( 24 y + 1 ) ( 24 y - 1 )}{6}

= \frac{\frac{( 24 y + 1 ) ( 24 y - 1 )}{6}}{6}

使用分式法则:

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

= \frac{( 24 y + 1 ) ( 24 y - 1 )}{6 \cdot 6}

数字相乘:

6 \cdot 6 = 36

= \frac{( 24 y + 1 ) ( 24 y - 1 )}{36}
