Fractional inequality, as razvesti fractional inequalities

Scheme the solution of the fractional inequalities

1. Using the method of intervals
   1. Move all members to one side
   2. Reduce to a common denominator, always keeping the denominator
   3. Rozvadov method of intervals
2. The use of equivalent transformations
1. Fix odz initial equation
2. Bring to mind and Rozvadov these inequalities for DHS initial or performed the equivalent transformation to introduce a convenient change of variables.
3. Perform background checks on substitution in the original equation

Equivalent transformation of simple fractional inequalities

An example of the solution of fractional inequalities method of intervals

1. DHS:
2. The zeros in because
3. Note the zeros at DHS and find the sign in each interval

Answer: or
