展开

\frac{( x - 6 ) ( x - 1 )}{( x + 10 ) ( x + 1 )}

\frac{x ^{2} - 7 x + 6}{x ^{2} + 11 x + 10}

求解步骤

\frac{( x - 6 ) ( x - 1 )}{( x + 10 ) ( x + 1 )}

乘开

(x + 10) (x + 1) : x^{2} + 11 x + 10

= \frac{( x - 6 ) ( x - 1 )}{x ^{2} + 11 x + 10}

乘开

(x - 6) (x - 1) : x^{2} - 7 x + 6

= \frac{x ^{2} - 7 x + 6}{x ^{2} + 11 x + 10}

e x p an d \frac{( x ^{2} - 4 ) ( 6 x + 3 )}{( x + 4 ) ( 6 x - 8 )}

e x p an d θ lo g_{10} (1 - \frac{x}{θ})

e x p an d \frac{\frac{d}{d x} ( 1 )}{( 1 + x ) ^{3}}

e x p an d L i + a (\frac{d _{1}}{d _{1} + d _{2}})

e x p an d \frac{a - b}{b - a ( b - a )}
