Apply Range Constraint:
For real values of 
, we must satisfy 
. This simplifies to
Verify the Inequality:
Since 
and 
are always non-negative real numbers, the inequality 
is always true for any real parameters 
and 
.
Check the Denominator Constraints:
The expression only breaks down if it becomes mathematically undefined or collapses
Denominator cannot be zero: 
Parameters must be active non-zero variables:
