Step-by-step explanation:
.
Hence, there are two possibilities to consider:
- Either
, - Or
.
If
, then
.
Substitute into the original equation:
. Solve for
:
.
Important: verify that the solution
meet the assumption
. Indeed,
and is indeed non-negative. Hence, the solution
is valid.
On the other hand, if
, then
.
Substitute into the original equation:
. Solve for
:
.
Similarly, verify that the solution
satisfies the current assumption that
. Indeed, this assumption is met, and
is also a valid solution.
