Solve:
Solution
The domain is defined by the function and is equal to
(of course
, i.e.
, or
, i.e.
).
We work out the equation:
We substitute into the equation:
and get:
This equation can be factorized:
and has the solutions:
or
Thus the corresponding solutions for are:
and thus
and thus
Both solutions lie in the domain and are valid.
