[ 1/1Inequality]
Assignment:Find the solution set of inequality -m-√(m²+8) >-3/4 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
-m - √ ( m ^ 2 + 8 ) > -3 / 4 (1)
From the definition field of √
x ^ 2 + 8 ≥ 0 (2 )
From inequality(1):
m < -4.958333
From inequality(2):
m ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
From inequalities (1) and (2)
m < -4.958333 (3)
The final solution set is :
m < -4.958333Your problem has not been solved here? Please take a look at the hot problems !
