Assignment:Find the solution set of inequality (3k^3-3k+6)/(k^3-2) >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 3 * k ^ 3 - 3 * k + 6 ) / ( k ^ 3 - 2 ) >0 (1)
From the definition field of divisor
x ^ 3 - 2 ≠ 0 (2 )
From inequality(1):
k < -1.52138 或 k > 1.259921
From inequality(2):
k < 1.259921 或 k > 1.259921
From inequalities (1) and (2)
k < -1.52138 或 k > 1.259921 (3)
The final solution set is :
k < -1.52138 或 k > 1.259921Your problem has not been solved here? Please take a look at the hot problems !
