[ 1/1Inequality]
Assignment:Find the solution set of inequality -1000 ≤6.46/[1.44x*x-10.56x+18.64] .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
-1000 ≤6.46 / ( 1.44 * x * x - 10.56 * x + 18.64 ) (1)
From the definition field of divisor
1.44 * x * x - 10.56 * x + 18.64 ≠ 0 (2 )
From inequality(1):
x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
From inequality(2):
x < 2.95956 或 2.95956 < x < 4.373773 或 x > 4.373773
From inequalities (1) and (2)
x < 2.95956 或 2.95956 < x < 4.373773 或 x > 4.373773 (3)
The final solution set is :
x < 2.95956 或 2.95956 < x < 4.373773 或 x > 4.373773Your problem has not been solved here? Please take a look at the hot problems !
