Assignment:Find the solution set of inequality sqrt(x^2+3x) >sqrt(2) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
sqrt ( x ^ 2 + 3 * x ) > sqrt ( 2 ) (1)
From the definition field of √
x ^ 2 + 3 * x ≥ 0 (2 )
From inequality(1):
x < -3.561553 或 x > 0.561553
From inequality(2):
x ≤ -3 或 x ≥ 0
From inequalities (1) and (2)
x < -3.561553 或 x > 0.561553 (3)
The final solution set is :
x < -3.561553 或 x > 0.561553Your problem has not been solved here? Please take a look at the hot problems !
