\"\"

\

The inequality is \"\".

\

Solve the inequality.

\

\"\"                      (Original inequality)

\

\"\"     (Add \"\" to each side)

\

\"\"                     (Apply additive inverse property: \"\")

\

\"\"                             (Add: \"\")

\

\"\"                        (Divide each side by \"\")

\

\

A dot means that this point is included in the solution set.

\

\"\"

\

Check solution for \"\"-value.

\

Case(i): \"\"

\

\"\"                    (Original inequality)

\

\"\"                  (Substitute \"\")

\

\"\"                    (Multiply)

\

\"\"                            (Subtract: \"\")

\

Therefore, \"\" is true inequality.
