化简 (x-5/3)(x-2/3)

解答

化简

(x - \frac{5}{3}) (x - \frac{2}{3})

\frac{( 3 x - 5 ) ( 3 x - 2 )}{9}

求解步骤

(x - \frac{5}{3}) (x - \frac{2}{3})

化简

x - \frac{5}{3} : \frac{3 x - 5}{3}

= \frac{3 x - 5}{3} (x - \frac{2}{3})

使用分式法则:

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

= \frac{( 3 x - 5 ) ( x - \frac{2}{3} )}{3}

化简

(3 x - 5) (x - \frac{2}{3}) : \frac{( 3 x - 5 ) ( x \cdot 3 - 2 )}{3}

= \frac{\frac{( 3 x - 5 ) ( x \cdot 3 - 2 )}{3}}{3}

使用分式法则:

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

= \frac{( 3 x - 5 ) ( x \cdot 3 - 2 )}{3 \cdot 3}

数字相乘:

3 \cdot 3 = 9

= \frac{( 3 x - 5 ) ( x \cdot 3 - 2 )}{9}

= \frac{( 3 x - 5 ) ( 3 x - 2 )}{9}

e x p an d (- 6 sin (t) + 64) (4 π 13)

e x p an d \frac{( 1 - 2 x ) ( 3 - 4 y )}{6}

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

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

e x p an d \frac{( ( n ^{2} x ^{2} - 2 ) sin ( n x ) + 2 n x cos ( n x ) )}{n ^{3}}
