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