[ 1/1Inequality]
Assignment:Find the solution set of inequality 1.5x+(2.5x*x*x/(4-x*x))-x*x+4 <0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
1.5 * x + ( 2.5 * x * x * x / ( 4 - x * x ) ) - x * x + 4 <0 (1)
From the definition field of divisor
4 - x * x ≠ 0 (2 )
From inequality(1):
x < -3.439733 或 -2 < x < -1.093286 或 x > 2
From inequality(2):
x < -2 或 -2 < x < 2 或 x > 2
From inequalities (1) and (2)
x < -3.439733 或 -2 < x < -1.093286 或 x > 2 (3)
The final solution set is :
x < -3.439733 或 -2 < x < -1.093286 或 x > 2Your problem has not been solved here? Please take a look at the hot problems !
