化简 (x-94/9)(x-12)(x-10)

解答

化简

(x - \frac{94}{9}) (x - 12) (x - 10)

\frac{( 9 x - 94 ) ( x - 12 ) ( x - 10 )}{9}

求解步骤

(x - \frac{94}{9}) (x - 12) (x - 10)

化简

x - \frac{94}{9} : \frac{9 x - 94}{9}

= \frac{9 x - 94}{9} (x - 12) (x - 10)

使用分式法则:

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

= \frac{( 9 x - 94 ) ( x - 12 ) ( x - 10 )}{9}

e x p an d 6 t (5 - 4 t)^{7} d t

e x p an d \frac{u ^{5} ( t ) ( t - 5 ) - u ^{10} ( t ) ( t - 10 )}{5}

e x p an d \frac{( ( 8 n ^{2} + 5 ) ( - 5 ) ^{n} )}{8 ^{n + 5}}

e x p an d (1 + y) 1 + y^{2}

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