Assignment:Find the solution set of inequality sqrt(x^2+3x-4) >x+1 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
sqrt ( x ^ 2 + 3 * x - 4 ) > x + 1 (1)
From the definition field of √
x ^ 2 + 3 * x - 4 ≥ 0 (2 )
From inequality(1):
x > 5
From inequality(2):
x ≤ -4 或 x ≥ 1
From inequalities (1) and (2)
x > 5 (3)
The final solution set is :
x > 5Your problem has not been solved here? Please take a look at the hot problems !
