On the inequality of X, the solution set of root x > ax + 1.5 is {x | 4

On the inequality of X, the solution set of root x > ax + 1.5 is {x | 4

Let the root sign x = y
The result is Y > ay2 + 1.5
Because the solution set is (4, b)
SO 2 and the radical B are two of ay2-y + 1.5 = 0
Substituting y = 2
A = 1 / 8
The solution is b = 36
