Either or .
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.
