We do not know if (2x-3) is positive or negative.
Find critical points or point, treating first the equality.
Change to "=", and solve to find critical point:
.
x=7/3, critical point.
2 is less than the critical point, and 3 is greater than the critical point. They are just examples. The values are not too important; just they are on specific intervals of the real line based on the found critical point.
Test using 2, for x<7/3
, and , so
is solution.
Test using 3, for x>7/3
, FALSE. This means x>7/3 are NOT solutions.
The solution is
