![**Problem 3: Finding and Classifying Relative Extrema**
**Objective:**
Find and classify all relative extrema for the function:
\[ f(x, y) = x^2 + y^2 + 2xy. \]
**Hint:**
If the second partial derivative test is inconclusive, use another method to classify the extrema.
---
**Detailed Explanation:**
To solve this problem, we need to use calculus techniques such as partial derivatives. The second partial derivative test may help determine whether points are local minima, maxima, or saddle points. If the test is inconclusive, we may need to explore alternative approaches such as analyzing level curves or considering the function's behavior analytically.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F31367789-01e4-4129-b30b-49084de51bdb%2F7a425c96-6f4c-4673-875b-b9ae982072c8%2Fgwdimqv_processed.png&w=3840&q=75)
