x/((x-6))>= 0

解答

\frac{x}{( x - 6 )} \geq 0

x \leq 0 or x > 6

间隔符号

(- \infty, 0] \cup (6, \infty)

求解步骤

\frac{x}{x - 6} \geq 0

确定区间

x \leq 0 or x > 6

\frac{4}{( x - 5 )} - \frac{2}{( x - 5 )} > \frac{( 3 x + 3 )}{( x ^{2} - 25 )}

- 4 - 3 x^{2} > 0

6 x^{3} + 7 x^{2} - 20 x > 0

\frac{( 2 x ^{2} )}{( x - 5 )} > - 5

\frac{3}{( x - 2 ) - 1} < 0
