sqrt(14 - 4*x) > 0
Detail solution
Given the inequality:
144x>0\sqrt{14 - 4 x} > 0
To solve this inequality, we must first solve the corresponding equation:
144x=0\sqrt{14 - 4 x} = 0
Solve:
Given the equation
144x=0\sqrt{14 - 4 x} = 0
so
144x=014 - 4 x = 0
Move free summands (without x)
from left part to right part, we given:
4x=14- 4 x = -14
Divide both parts of the equation by -4
x = -14 / (-4)

We get the answer: x = 7/2
x1=72x_{1} = \frac{7}{2}
x1=72x_{1} = \frac{7}{2}
This roots
x1=72x_{1} = \frac{7}{2}
is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
x0<x1x_{0} < x_{1}
For example, let's take the point
x0=x1110x_{0} = x_{1} - \frac{1}{10}
=
110+72- \frac{1}{10} + \frac{7}{2}
=
175\frac{17}{5}
substitute to the expression
144x>0\sqrt{14 - 4 x} > 0
144175>0\sqrt{14 - \frac{4 \cdot 17}{5}} > 0
