Assignment:Find the solution set of inequality sqrt(a^2-3a+2)+a >2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
sqrt ( a ^ 2 - 3 * a + 2 ) + a >2 (1)
From the definition field of √
x ^ 2 - 3 * x + 2 ≥ 0 (2 )
From inequality(1):
a > 2
From inequality(2):
a ≤ 1 或 a ≥ 2
From inequalities (1) and (2)
a > 2 (3)
The final solution set is :
