PRM II - Mock Exam 1 - Question 13

Postby rainer.behrens » Sun Oct 18, 2015 2:56 pm

Hi,

the solution to PRM II - Mock Exam 1 - Question 13 states
„The correct answer is B
Positive definite if ‘y’ is 0.The quadratic form is given by, This quadratic form is “Positive definite if ‘y’ is 0”.“

My problem is:
The sentence „The quadratic form is given by, “ is not completed. Can you give me the mentioned quadratic form?
Then I hope to understand the solution.

I calculate the following quadratic form:

3x^2 + 4y^2 + xy

Could you please check whether this is correct?

Thanks a lot

Best regards

Rainer
