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