Assignment:Find the solution set of inequality 2x+5/x^2+2x-35 ≥0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
2 * x + 5 / x ^ 2 + 2 * x - 35 ≥0 (1)
From the definition field of divisor
x ≠ 0 (2 )
From inequality(1):
-0.370214 ≤ x ≤ 0.386602 或 x ≥ 8.733612
From inequality(2):
x < 0 或 x > 0
From inequalities (1) and (2)
-0.370214 ≤ x < 0 或 0 < x ≤ 0.386602 或 x ≥ 8.733612 (3)
The final solution set is :
-0.370214 ≤ x < 0 或 0 < x ≤ 0.386602 或 x ≥ 8.733612Your problem has not been solved here? Please take a look at the hot problems !
