\

The equation is \"\".

\

Solve the equation.

\

\"\"                         (Original equation)

\

Case(i):

\

\"\"                           (First equation)

\

\"\"              (Subtract \"\" from each side)

\

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

\

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

\

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

\

\"\"                                 (Cancel common terms)

\

Case(ii):

\

\"\"                      (Second equation)

\

\"\"         (Subtract \"\" from each side)

\

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

\

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

\

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

\

\"\"                                 (Cancel common terms)

\

Therefore, the solutions are \"\" and \"\".
