[ 1/1Inequality]
Assignment:Find the solution set of inequality √(((1/4)x+√(48-15/16x^2))-x)^2+(3/4)x^2 >8 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
√ ( ( ( 1 / 4 ) * x + √ ( 48 - 15 / 16 * x ^ 2 ) ) - x ) ^ 2 + ( 3 / 4 ) * x ^ 2 >8 (1)
From the definition field of √
48 - 15 / 16 * x ^ 2 ≥ 0 (2 )
From the definition field of √
( ( 1 / 4 ) * x + √ ( 48 - 15 / 16 * x ^ 2 ) ) - x ≥ 0 (3 )
From inequality(1):
x < -0.819004 或 x > 1.920576
From inequality(2):
-16/√5 ≤ x ≤ 16/√5
From inequality(3):
x ≤ √32
From inequalities (1) and (2)
-16/√5 ≤ x < -0.819004 或 1.920576 < x ≤ 16/√5 (4)
From inequalities (3) and (4)
-16/√5 ≤ x < -0.819004 或 1.920576 < x ≤ √32 (5)
The final solution set is :
-16/√5 ≤ x < -0.819004 或 1.920576 < x ≤ √32 Your problem has not been solved here? Please take a look at the hot problems !
