(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

[tex]\int\int x^2 dA[/tex] where the area D is boundd by the ellipse 5x^2 + 4xy + y^2 = 1.

2. Relevant equations

3. The attempt at a solution

I'm not sure where to start this question. A few ideas I'm exploring are: 1. rewrite in polar co-ordinates (not sure how to write an ellipse in this form!), or 2. do a transformation from this ellipse to a circle (not sure how to do this either).

I anyone can suggest which method is more correct and get me started with a general idea of how to approach the problem, i would greatly appreciate it!

Thank you.
